ABSTRACT

Abstract Humans are exposed to natural compounds such as phytoestrogens primarily through diet and supplements. These compounds promote health by alleviating the symptoms and illnesses associated with menopause and arthritis. Diosgenin (DSG) occurs naturally in plants such as Dioscorea villosa (DV) and binds to estrogen receptors, so it may have similar effects to this hormone, including against arthritis. Thus, we investigated the effect of chronic treatment with dry extract of DV and its phytoestrogen DSG on ovariectomized mice with arthritis. We found that dry extract of Dioscorea villosa (DV) contains the phytoestrogen diosgenin (DSG) in its composition. Furthermore, arthritic mice treated with DV and DSG showed reduced neutrophil accumulation in the articular cartilage. Also, the dry extract of DV administered orally (v.o) did not alter the leukocyte count in the joints or promote changes in the reproductive tract. However, DSG altered these parameters, with possible beneficial effects by reducing symptoms related to reproductive aging. Thus, oral treatment with dry extract of DV and subcutaneous (s.c) treatment with DSG showed promise by acting against inflammation caused by arthritis and reducing symptoms in the reproductive tract due to menopause.

ABSTRACT

Introdução: O envelhecimento do terço superior da face se caracteriza por ptose da sobrancelha, rugas glabelares e rugas transversais frontais. O tratamento pode ser realizado através da frontoplastia coronal, da frontoplastia temporal com incisões limitadas e da frontoplastia endoscópica. O objetivo deste estudo é descrever a técnica de frontoplastia endoscópica subperiostal com miotomia dos músculos da região glabelar e fixação do retalho na fáscia temporal profunda, avaliando sua aplicabilidade e eficácia. Métodos: Foram avaliadas 24 pacientes, do sexo feminino, submetidas a frontoplastia endoscópica associada a blefaroplastia superior, com idade variando entre 37 e 72 anos, em um período de 10 anos. Medidas entre a distância da linha interpupilar e a porção superior da sobrancelha foram realizadas através de análise fotográfica com uso do sistema digital de imagem Mirror 6,0, na região medial, central e lateral de cada lado, no pré-operatório, e no pós-operatório de 6 meses. Resultados: A média de idade foi de 52 anos. Houve significância estatística (p<0,05) em todas as áreas da sobrancelha avaliadas, a média de foi de 0,3 cm mais alta. As complicações foram: 1 caso de extrusão fio, 1 caso de assimetria, 2 casos de correção insuficiente da sobrancelha e 2 casos de recidiva de rugas glabelares. Conclusão: A frontoplastia endoscópica subperiostal com miotomia dos músculos da região glabelar e flxação do retalho na fáscia temporal profunda com pontos demonstrou ser efetiva no tratamento do envelhecimento do terço superior da face, com resultados estatisticamente comprovados, baixa morbidade e bons resultados estéticos.


Introduction: The aging of the upper third of the face is characterized by ptosis of the eyebrow, glabellar wrinkles and frontal transverse wrinkles. Treatment can be performed through coronal frontoplasty, temporal frontoplasty with limited incisions and endoscopic frontoplasty. The aim of this study is to describe the technique of subperiosteal endoscopic frontoplasty with myotomy of the muscles of the glabellar region and fixation of the flap in the deep temporal fascia, evaluating its applicability and effectiveness. Methods: Twenty-four female patients who underwent endoscopic frontoplasty associated with upper blepharoplasty, aged between 37 and 72 years old, over a 10-year period were evaluated. Measurements between the distance from the inter-pupillary line and the upper portion of the eyebrow were performed through photographic analysis using the Mirror 6.0 digital image system, in the medial, central and lateral regions on each side, in the preoperative period, and in the 6 month postoperative period. Results: The average age was 52 years. There was statistical significance (p<0.05) in all evaluated eyebrow areas, the mean was 0.3 cm higher. Complications were: 1 case of wire extrusion, 1 case of asymmetry, 2 cases of insufficient correction of the eyebrow and 2 cases of recurrence of glabellar wrinkles. Conclusion: Subperiosteal endoscopic frontoplasty with myotomy of the muscles of the glabellar region and fixation of the flap in the deep temporal fascia with stitches, proved to be effective in the treatment of aging of the upper third of the face, with statistically proven results, low morbidity and good aesthetic results.

ABSTRACT

Introdução: A mastopexia com prótese continua sendo um desafio para todos os cirurgiões plásticos. Resultados consistentes ainda são difíceis de se obter por muitas razões e alguns autores defendem a cautela devido a complicações. Métodos: Este estudo retrospectivo inclui 92 casos consecutivos mastopexia de aumento em tempo único realizados pelo mesmo cirurgião, entre março de 2012 e outubro de 2019. Resultados: O seguimento médio foi de 14 meses para o grupo de mastopexia de aumento. Três pacientes (3,3%) tiveram contratura capsular grau III. O índice de revisões foi de 25,3%: 7,6% com recidiva da ptose, revisão de cicatrizes em 6,5%, 1,1% de assimetrias. Três pacientes (3,3%) apresentaram ruptura da fixação da alça muscular, quatro pacientes (4,4%) tiveram deformidades dinâmicas. Conclusão: A técnica modificada de duplo espaço apresenta em nossa experiência resultados consistentes a longo prazo, e as taxas de revisão/complicação foram semelhantes a alguns estudos, mas maiores do que outros. Cirurgia prévia da mama, tabagismo, amamentação e cirurgia bariátrica anterior não aumentam as taxas de complicações e revisões. Pode ser uma das opções para a cobertura e suporte dos implantes em procedimentos de mastopexia de aumento.


Introduction: Mastopexy with prosthesis remains a challenge for all plastic surgeons. Consistent results are still difficult to obtain for many reasons, and some authors advocate caution due to complications. Methods: This retrospective study includes 92 consecutive single-stage augmentation mastopexy cases performed by the same surgeon between March 2012 and October 2019. Results: The median follow-up was 14 months for the augmentation mastopexy group. Three patients (3.3%) had grade III capsular contracture. The revision rate was 25.3%: 7.6% with ptosis recurrence, scar revision in 6.5%, and 1.1% asymmetries. Three patients (3.3%) had ruptured muscle loop fixation, four patients (4.4%) had dynamic deformities. Conclusion: The modified double-space technique in our experience shows consistent long-term results, and revision/complication rates were similar to some studies but higher than others. Prior breast surgery, smoking, breastfeeding, and previous bariatric surgery do not increase rates of complications and revisions. It can be one of the options for covering and supporting implants in augmentation mastopexy procedures.

ABSTRACT

ABSTRACT Objectives: Non-small cell lung cancer (NSCLC) is an incidental and aggressive type of cancer. Although curative treatment can be offered, the recurrence rate is relatively high. Identifying factors that have a prognostic impact may guide changes in the staging system and recommendations for adjuvant therapy. The aim of this study was to evaluate the impact of microvascular invasion on the 5-year overall survival (OS) of patients with resected NSCLC treated at a reference cancer center. Methods: This retrospective, observational cohort study included patients diagnosed with early-stage NSCLC (clinical stages I-IIIA), treated with curative-intent surgery at the Brazilian National Cancer Institute between 2010 and 2016. Results: The dataset comprised 91 surgical patients, mostly females and white, with a mean age of 62 years (range between 29-83). Cases were distributed as stages I, II, and III in 55%, 29%, and 16%. Adenocarcinoma was the predominant histological subtype (67%), and microvascular invasion was present in 25% of the patients. The 5-year OS probability was 60% (95% CI, 48.3-68.9). Among all characteristics, advanced stages (p = 0.001) and the presence of microvascular invasion (p< 0.001) were related to a worse 5-year OS. After adjusting for age group and pathological stage, the presence of microvascular invasion was associated with a 4-fold increased risk of death (HR 3.9, 95% CI, 1.9-8.2). Conclusion: The presence of microvascular invasion was an independent factor related to worse survival and, therefore, should be routinely assessed in resected specimens.


RESUMO Objetivos: O câncer de pulmão não pequenas células (CPNPC) é um tipo incidental e agressivo de câncer. Embora o tratamento curativo possa ser oferecido, a taxa de recidiva é relativamente alta. A identificação de fatores que têm impacto prognóstico pode orientar mudanças no TNM e recomendações para terapia adjuvante. O objetivo deste estudo foi avaliar o impacto da invasão microvascular na sobrevida global (SG) em 5 anos de pacientes com CPNPC ressecado tratados em um centro de referência em câncer. Métodos: Este estudo de coorte retrospectivo e observacional incluiu pacientes diagnosticados com CPNPC em estágio inicial (estágios clínicos I-IIIA), tratados com cirurgia com intenção curativa no Instituto Nacional de Câncer entre 2010 e 2016. Resultados: Foram incluídos 91 pacientes tratados com cirurgia, a maioria mulheres e brancos, com média de idade de 62 anos (variação entre 29-83). Os casos foram distribuídos em estágios I, II e IIIA em 55%, 29% e 16%. Adenocarcinoma foi o subtipo histológico predominante (67%), e a invasão microvascular esteve presente em 25% dos pacientes. A probabilidade de SG em 5 anos foi de 60% (IC 95%, 48,3-68,9). Dentre todas as características analisadas, estágios mais avançados (p = 0,001) e a presença de invasão microvascular (p < 0,001) foram relacionados a uma pior SG em 5 anos. Após ajustar para faixa etária e estágio patológico, a presença de invasão microvascular foi associada a um aumento de 4 vezes no risco de morte (RR 3,9, IC 95%, 1,9-8,2). Conclusão: A presença de invasão microvascular foi um fator independente relacionado a uma pior sobrevida e, portanto, deve ser avaliada rotineiramente em espécimes ressecados.

ABSTRACT

ABSTRACT Objective: The aim of this study was to describe the real-world experience multikinase inhibitors (MKI) in the treatment advanced differentiated thyroid carcinoma (DTC) refractory to radioactive iodine (RAIR) therapy. Subjects and methods: We reviewed the records of all patients with MKI-treated DTC from 2010 to 2018. Progression free survival (PFS), response rates (RR) and adverse events (AE) profiles were assessed. Clinical parameters were compared between groups with different outcomes (disease progression and death) to identify possible prognostic factors and benefit from treatment. Results: Forty-four patients received MKI for progressive RAIR DTC. Median PFS was 24 months (10.2-37.7) and median overall survival (OS) was 31 months. Best overall response was complete response in one patient (4.5%), partial response in nine (20.4%), stable disease in twenty-two (50%), and progressive disease (PD) in twelve (27.3%). Seventy-two point 7 percent patients had clinical benefit and AE were mild in most cases (82.7%). Progressive patients were more likely to have FDG positive target lesion than those who did not progress (p = 0.033) and higher maximum SUV on target lesions (p = 0.042). Presence of lung-only metastasis and lower thyroglobulin (Tg) during treatment was associated with stable disease (p = 0.015 and 0,049, respectively). Patients with shorter survival had larger primary tumor size (p = 0.015) and higher maximum SUV on target lesions (p = 0.023). Conclusion: Our findings demonstrate safety and effectiveness of MKI in patients with advanced RAIR DTC. We were able to identify as possible prognostic markers of better outcomes: absence of FDG uptake on target lesions, lower maximum SUV on PET-CT, presence of lung-only metastasis and lower Tg during treatment.

ABSTRACT

RESUMO: Fundamentos e objetivos: Apesar dos reconhecidos benefícios da prática de atividade física em pacientes com doença cardiovascular, acredita-se que pacientes com insuficiência cardíaca e fração de ejeção reduzida com comportamento não sedentário, mesmo que não pratiquem exercício físico regular, apresentem melhora da função cardiovascular e qualidade de vida em comparação a pacientes sedentários. Objetivo: comparar a capacidade funcional, função ventricular e quali-dade de vida de pacientes com insuficiência cardíaca sedentários e não sedentários. Métodos: Foram avaliados pacientes com Insuficiência Cardíaca e Fração de ejeção <50%, sendo compostos dois grupos, sedentários (n=45) e não sedentários (n=36), de acordo com o Questionário Internacional de Atividade Física. Os grupos foram submetidos à avaliação clínica e de qualidade de vida, teste de caminhada de Cooper, ecocardiograma e comparação pelo teste Qui-Quadrado para variáveis categóricas ou teste T de Student ou Mann-Whitney para variáveis contínuas. Nível de significância de 5%. Resultados: Os grupos foram homogêneos em relação às características basais e etiologia. Os pacientes do Grupo Não Sedentário apre-sentaram menos sintomas limitantes (p<0,01), menor necessidade de digitálicos (p=0,02), melhor fração de encurtamento ventricular (p=0,03) e menor aumento do volume indexado do átrio esquerdo (p=0,004). Não foram encontradas diferen-ças no teste de caminhada entre os grupos. Houve maior prejuízo do quesito capacidade funcional da qualidade de vida do grupo Sedentário. Conclusão: Considerando a limitação da amostra, pacientes com insuficiência cardíaca e comporta-mento não sedentário apresentam maior tolerabilidade ao exercício por apresentarem sintomas menos limitantes, melhor função ventricular e melhor qualidade de vida no quesito capacidade funcional quando comparados a pacientes sedentáriosRESUMOFundamentos e objetivos: Apesar dos reconhecidos benefícios da prática de atividade física em pacientes com doença cardiovascular, acredita-se que pacientes com insuficiência cardíaca e fração de ejeção reduzida com comportamento não sedentário, mesmo que não pratiquem exercício físico regular, apresentem melhora da função cardiovascular e qualidade de vida em comparação a pacientes sedentários.

ABSTRACT: Purpose: Despite the recognized benefits of practicing physical activity in patients with cardiovascular disease, it is believed that patients with heart failure and reduced ejection fraction with non-sedentary behavior may present an improvement in cardiovascular function and quality of life compared to sedentary patients, even if they do not practice regular physical ex-ercise. The aim of the present study was to compare functional capacity, systolic and diastolic cardiac function and quality of life of sedentary and non-sedentary patients with heart failure and reduced ejection fraction. Methods: Patients with heart failure and ejection fraction below 50% were divided into two groups, Sedentary (n = 45) and Non-Sedentary (n = 36), using the IPAQ questionnaire. These two groups were evaluated with clinical evaluation, quality of life SF-36 questionnaire, Cooper walking test and transthoracic echocardiography. They were compared by Chi-Square test for categorical variables or Test T or Man-Whitney for continuous variables; the level of significance adopted in the statistical analysis was 5%. Results: The groups were homogeneous in relation to the baseline characteristics and etiology. The Non-Sedentary Group had fewer patients with severe symptoms (p <0.01), less necessity of digitalis (p = 0.02) and better left ventricle fractional shorten-ing (p = 0.03). There was no apparent difference in the walk-test data between groups. Additionally, there was a greater impairment in the functional capacity of the SF-36 Questionnaire in the Sedentary Group. Conclusion: Considering the sample limitation, patients with heart failure and non-sedentary behavior have greater tolerability to exercise because they have fewer limiting symptoms and better quality of life in the functional capacity domain than sedentary patients.

ABSTRACT

A lipoaspiração é um dos procedimentos mais comuns na especialidade de cirurgia plástica. No levantamento da ISAPS de 2018 foi a segunda cirurgia mais realizada em todo o mundo. Devido aos movimentos repetitivos próprios da cirurgia, fricção importante é gerada no local e as consequências são queimaduras cutâneas que podem deixar cicatrizes inestéticas e discromias. O objetivo deste estudo é criar um protótipo de um dispositivo protetor da pele, a partir de um modelo antigo, que sirva a esse propósito, e observar sua funcionalidade e os efeitos da sua utilização na pele de suínos. Os testes foram realizados em animais mortos sem sofrimento disponibilizados pelo setor de Medicina Veterinária da Universidade Positivo. Foram feitas três incisões no abdome do animal para passagem da cânula de lipoaspiração e outras três para a inserção e utilização do protótipo, bem como para comparação com o dispositivo modelo. O tempo estabelecido de movimentos de lipoaspiração foi de vinte minutos, realizados com a cânula de 5mm diretamente em contato com a pele e dentro do protótipo. Foi avaliada a ergonomia do protótipo, facilidade de inserção e travamento adequado na pele com diferentes trações. Observação e avaliação da pele após os procedimentos e medição (cm) das incisões foram realizadas. O protótipo do dispositivo protetor cutâneo de lipoaspiração criado apresentou fácil manuseio e mecanismo de travamento na pele mais eficiente quando comparado ao modelo utilizado. A incisão cutânea para uso do protótipo foi ligeiramente maior e a pele não apresentou sinais de queimadura.


Liposuction is one of the most common procedures in the plastic surgery specialty. In the 2018 ISAPS survey, it was the second most performed surgery worldwide. Due to the repetitive movements typical of the surgery, significant friction is generated at the site, and the consequences are skin burns that can leave unsightly scars and dyschromias. This study aims to create a skin protective device prototype from an old model, which serves this purpose, and to observe its functionality and its effects on the pigskin. The tests were carried out on dead animals without suffering provided by the Veterinary Medicine sector at Universidade Positivo. Three incisions were made in the animal's abdomen to pass the liposuction cannula and another three for the insertion and use of the prototype to compare it with the model device. The established time for liposuction movements was twenty minutes, performed with the 5mm cannula directly in contact with the skin and inside the prototype. The prototype's ergonomics, ease of insertion, and good locking on the skin with different tractions were evaluated. Observation and evaluation of the skin were performed after procedures and incisions' measurements (cm). The cutaneous liposuction protective device prototype presented easy handling and a more efficient skin locking mechanism than the model used. The skin incision for using the prototype was slightly larger, and the skin showed no burning signs.

ABSTRACT

Resumo Fundamento A síndrome de takotsubo (takotsubo) é uma forma de cardiomiopatia adquirida. Dados nacionais sobre essa condição são escassos. O Registro REMUTA é o primeiro a incluir dados multicêntricos dessa condição no nosso país. Objetivo Descrever as características clínicas, prognóstico, tratamento intra-hospitalar e mortalidade hospitalar e em 1 ano de seguimento. Métodos Estudo observacional, retrospectivo, tipo registro. Incluídos pacientes internados com diagnóstico de takotsubo ou que desenvolveram esta condição durante internação por outra causa. Os desfechos avaliados incluíram fator desencadeador, análise dos exames, uso de medicações, complicações e óbito intra-hospitalar e em 1 ano de seguimento. O nível de significância adotado foi de 5%. Resultados Foram incluídos 169 pacientes, em 12 centros no Estado do Rio de Janeiro. A idade média foi de 70,9 ± 14,1 anos e 90,5% eram do sexo feminino; 63% dos casos foram de takotsubo primário e 37% secundário. Troponina I foi positiva em 92,5% dos pacientes e a mediana de BNP foi de 395 (176,5; 1725). Supradesnivelamento do segmento ST esteve presente em 28% dos pacientes. A fração de ejeção do ventrículo esquerdo teve mediana de 40 (35; 48)%. Observamos taxa de 25,7% de ventilação mecânica invasiva e 17,4% de choque. Suporte circulatório mecânico foi utilizado em 7,7%. A mortalidade intra-hospitalar foi de 10,6% e a mortalidade ao final de 1 ano foi de 16,5%. Takotsubo secundário e choque cardiogênico foram preditores independentes de mortalidade. Conclusão Os resultados do REMUTA mostram que takotsubo não se trata de patologia benigna como se pensava, especialmente no grupo de takotsubo secundário que acarreta elevada taxa de complicações e de mortalidade.

Abstract Background Takotsubo syndrome (TTS) is an acquired form of cardiomyopathy. National Brazilian data on this condition are scarce. The Takotsubo Multicenter Registry (REMUTA) is the first to include multicenter data on this condition in Brazil. Objective To describe the clinical characteristics, prognosis, in-hospital treatment, in-hospital mortality, and mortality during 1 year of follow-up. Methods This is an observational, retrospective registry study including patients admitted to the hospital with diagnosis of TTS and patients admitted for other reasons who developed this condition. Evaluated outcomes included triggering factor, analysis of exams, use of medications, complications, in-hospital mortality, and mortality during 1 year of follow-up. A significance level of 5% was adopted. Results The registry included 169 patients from 12 centers in the state of Rio de Janeiro, Brazil. Mean age was 70.9 ± 14.1 years, and 90.5% of patients were female; 63% of cases were primary TTS, and 37% were secondary. Troponin I was positive in 92.5% of patients, and median BNP was 395 (176.5; 1725). ST-segment elevation was present in 28% of patients. Median left ventricular ejection fraction was 40 (35; 48)%. We observed invasive mechanical ventilation in 25.7% of cases and shock in 17.4%. Mechanical circulatory support was used in 7.7%. In-hospital mortality was 10.6%, and mortality at 1 year of follow-up was 16.5%. Secondary TTS and cardiogenic shock were independent predictors of mortality. Conclusion The results of the REMUTA show that TTS is not a benign pathology, as was once thought, especially regarding the secondary TTS group, which has a high rate of complications and mortality.

ABSTRACT

Abstract Objective: To evaluate and reconstruct three-dimensional images of vascularization along the fallopian tube (FT), as well as to determine its relationship with the ovary and ovarian fimbria, and to quantify the blood vessels along the FT according to its anatomical segments, using confocal microtomography (micro-CT). Materials and Methods: Nine specimens (six FTs and three FTs with ovaries) were fixed in a solution of 10% formalin for > 24 h at room temperature. Iodine staining was performed by soaking the specimens in 10% Lugol's solution for 24 h. All specimens were evaluated using micro-CT. A morphometric analysis was performed on the reconstructed images to quantify the vascular distribution along the FT. Results: In the FTs evaluated, the density of blood vessels was significantly greater in the fimbrial segments than in the isthmic segments (p < 0.05). The ovarian fimbria was clearly identified, demonstrating the important relationship between these vessels and the FT fimbriae. Conclusion: We believe that the vascularization in the fimbriae is greater than and disproportional that in the other segments of FT, and that the ovarian fimbria plays an important role in the development of that difference.


Resumo Objetivo: Avaliar e reconstruir imagens tridimensionais da vascularização ao longo da trompa de Falópio (TF) e sua relação com o ovário e fímbria do ovário, além de quantificar os vasos sanguíneos ao longo da TF de acordo com seus segmentos anatômicos usando microtomografia confocal (micro-TC). Materiais e Métodos: Nove espécimes (seis com TFs e três com TFs e ovários) foram fixados em solução de formol a 10% por mais de 24 h à temperatura ambiente. A coloração com iodo foi realizada usando solução de Lugol a 10% durante 24 h. Todos os espécimes foram avaliados usando micro-TC. Uma análise morfométrica foi realizada nas imagens reconstruídas para quantificar a distribuição vascular ao longo da TF. Resultados: A densidade dos vasos sanguíneos nas fímbrias foi significativamente aumentada em comparação ao segmento ístmico da TF (p < 0,05). A fímbria ovariana foi claramente identificada, demonstrando importante relação entre esses vasos e as fímbrias da TF. Conclusão: Acreditamos que as fímbrias apresentam vascularização aumentada e desproporcional em comparação com os demais segmentos da TF e que a fímbria ovariana desempenha importante papel nessa diferença.

ABSTRACT

Objetivo: O câncer de pulmão (CP), segundo dados da Organização Mundial de Saúde, é a neoplasia mais frequente e mais letal em homens e a segunda nas mulheres em todo o mundo. O CP compreende vários tipos histológicos, incluindo câncer de pulmão de pequenas células e os diferentes tipos de câncer de pulmão de não pequenas células (CPNPC). Esse subtipo representa cerca de 80% dos casos e compreende principalmente o adenocarcinoma. A terapia de escolha para tratamento de CPNPC com mutação no receptor do fator de crescimento epidérmico (EGFR) são os inibidores de tirosina quinase (ITKs), como erlotinibe e gefitinibe. Neste artigo avaliamos o custo-efetividade do erlotinibe comparado ao gefitinibe no tratamento de CPNPC. Métodos: Foi realizada uma análise de custo-efetividade sob a perspectiva de um hospital federal do Sistema Único de Saúde (SUS). Em um modelo de árvore de decisão, foram aplicados os desfechos de efetividade e segurança dos ITKs. Os dados clínicos foram extraídos de prontuários e os custos diretos, consultados em fontes oficiais do Ministério da Saúde. Resultados: O custo de 10 meses de tratamento, englobando o valor dos ITKs, procedimentos e manejo de eventos adversos, foi de R$ 63.266,76 para o erlotinibe e de R$ 39.594,72 para o gefitinibe. Os medicamentos apresentaram efetividade estatisticamente equivalente e diferença estatisticamente significativa para o desfecho de segurança, no qual o gefitinibe obteve melhor resultado. Conclusão: O gefitinibe, nesse contexto, é a tecnologia dominante quando os custos de tratamento são associados aos de manejo de eventos adversos.


Objective: According to the World Health Organization (WHO), lung cancer (LC) is the most common and lethal neoplasm in men and the second most common in women worldwide. The LC comprises several histological types, including small cell lung cancer and the different types of non-small cell lung cancer (NSCLC). This subtype represents about 80% of the cases and mainly comprises adenocarcinoma. The therapy of choice for epidermal growth factor receptor (EGFR) mutant NSCLC are tyrosine kinase inhibitors (TKI), like erlotinib and gefitinib. In this article, we evaluate the cost-effectiveness of erlotinib in comparison to gefitinib. Methods: A cost-effectiveness analysis was performed from the perspective of a Sistema Único de Saúde (SUS) federal hospital. In a decision tree model, the effectiveness and safety outcomes of TKIs were applied. The clinical data were extracted from the medical records and the direct costs consulted in official sources of the Ministry of Health. Results: The cost of 10 months of processing, encompassing the TKI value, procedures and resources of adverse events was R$ 63.266,76 for the year and R$ 39.594,72 for gefitinib. Forging cards have equal and statistically significant effectiveness for the safety outcome. Conclusion: Gefitinib, in this context, is a dominant technology when process costs are associated with those of managing adverse event.

ABSTRACT

New cases of the novel coronavirus disease 2019 (COVID-19), also known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), continue to rise worldwide following the declaration of a pandemic by the World Health Organization (WHO). The current pandemic has completely altered the workflow of health services worldwide. However, even during this critical period, patients with other diseases, like cancer, need to be properly treated. A few reports have shown that mortality due to SARS-CoV-2 is higher in elderly patients and those with other active comorbidities, including cancer. Patients with lung cancer are at risk of pulmonary complications from COVID-19, and as such, the risk/benefit ratio of local and systemic anticancer treatment has to be considered. For each patient, several factors, including age, comorbidities, and immunosuppression, as well as the number of hospital visits for treatment, can influence this risk. The number of cases is rising exponentially in Brazil, and it is important to consider the local characteristics when approaching the pandemic. In this regard, the Brazilian Thoracic Oncology Group has developed recommendations to guide decisions in lung cancer treatment during the SARS-CoV-2 pandemic. Due to the scarcity of relevant data, discussions based on disease stage, evaluation of surgical treatment, radiotherapy techniques, systemic therapy, follow-up, and supportive care were carried out, and specific suggestions issued. All recommendations seek to reduce contagion risk by decreasing the number of medical visits and hospitalization, and in the case of immunosuppression, by adapting treatment schemes when possible. This statement should be adjusted according to the reality of each service, and can be revised as new data become available.

ABSTRACT

OBJECTIVES: To evaluate the molecular testing and treatment patterns in a retrospective cohort of newly diagnosed treatment-naïve patients with locally advanced or metastatic non-small-cell lung cancer (NSCLC). METHODS: This is an observational retrospective cohort study conducted across 10 cancer centers in Brazil. Treatment-naïve patients with locally advanced or metastatic NSCLC were enrolled from January to December 2014. The following data were collected from the medical records of patients from diagnosis until the last record (death, loss to follow-up, or the end of the maximum follow-up period): demographics; medical history; smoking status; disease characteristics; previous treatments; and molecular testing patterns and results. The overall survival (OS) was also estimated. Results: A total of 391 patients from 8 different Brazilian states were included, with a median age of 64.1 years (23.7-98.7), with most patients being males (60.1%). The smoking status of 74.2% of patients was a 'former' or 'current smoker'. Stage IV NSCLC at diagnosis was observed in 82.4% of patients, with 269 of them (68.8%) presenting adenocarcinoma (ADC). Among the stage IV ADC patients, 54.0% were referred for molecular testing. Among the patients with an available epidermal growth factor receptor (EGFR) mutation status, 31 (24.0%) were EGFR-positive. The first-line treatment was a platinum-based chemotherapy for 98 patients (25.1%), while non-platinum-based regimens were used in 54 patients (13.8%). OS data were available for 370 patients, with a median OS of 10.8 months. Never smokers had a significantly higher median OS versus current or former smokers (14.6 versus 9.1 months; log-rank p=0.003). Among the patients for whom molecular testing data were available, those with EGFR-positive results had a longer median OS (34.6 versus 12.8 months; log-rank p=0.003). Conclusion: Our findings provide relevant information for prescribers and policy decision-makers by highlighting the unmet needs of patients and the importance of molecular testing in newly diagnosed locally advanced or metastatic lung adenocarcinoma. We also highlight the respective EGFR-tyrosine kinase inhibitor treatment when the result is positive and the areas in which further efforts are required to grant access to effective treatment.

ABSTRACT

Objetivo: Avaliar o impacto clínico e econômico do uso do perfil genômico utilizando Next Generation Sequencing (NGS) em DNA circulante tumoral (ctDNA) na escolha do tratamento de primeira linha (1L) dos pacientes com câncer de pulmão de células não pequenas, não escamoso, metastático e que não apresentam material tecidual suficiente para avaliação das mutações oncogênicas. Métodos: Foi realizada uma análise de custo-efetividade com base em um modelo de árvore de decisão e um modelo de Markov para simular os resultados dos testes diagnósticos e consequentemente o seu impacto clínico e econômico na primeira linha de tratamento. O comparador da análise foi o teste de mutações específicas no gene EGFR por ctDNA. As terapias medicamentosas incluídas na análise foram as terapias-alvo de EGFR e ALK, que estão incorporadas no rol da Agência Nacional de Saúde Suplementar, e a imunoterapia pembrolizumabe combinada à quimioterapia. Os desfechos clínicos foram retirados dos estudos clínicos das terapias avaliadas no modelo. Resultados: O uso do painel de NGS em ctDNA demonstrou uma economia de -R$ 2.076,35 por paciente em um ano, e os resultados de RCEI foram: -R$ 7.652,56 (R$/SLP) e -R$ 33.742,14 (R$/SG). Conclusão: O painel de NGS em ctDNA demonstrou ser uma alternativa dominante em relação ao teste de EGFR em ctDNA.


Objective: The aim of this study was to evaluate the clinical and economic impact of the next generation sequencing (NGS) panel of circulating tumor DNA (ctDNA) in the clinical decision of first line treatment for patients with metastatic non-squamous non-small cell lung cancer who lack of tissue material for evaluation of oncogenic driver mutations. Methods: A cost-effectiveness analysis was performed based on a decision tree model and a Markov model in order to simulate the results of diagnostic tests and therefore its clinical and economic impact in the first line of treatment. The comparators were the single EGFR mutation detection methodologies in ctDNA. The analysis included the anti-EGFR and anti-ALK target therapies; and the combined therapy of pembrolizumab plus chemotherapy. Clinical outcomes were derived from clinical trials of the therapies included in the model. Results: The use of the NGS ctDNA panel showed a saving of -R$ 2,076.35 and the results of the ICER were -R$ 7,652.56 (R$/SLP) and -R$ 33,742.14 (R$/SG). Conclusion: The NGS panel demonstrated to be a dominant alternative in comparison to ctDNA EGFR testing.

ABSTRACT

The World Health Organization (WHO) recommends as a weekly "target dose" of exercise 150 minutes of moderate exercise or 75 minutes of intense exercise. Public health policies have prioritized the practice of exercise as a strategy for disease prevention and health promotion, with health professionals as their main promoters. Objective: To assess the interaction between the amount of exercise per week and the knowledge about recommendations for fighting a sedentary lifestyle among health care professionals attending a congress of cardiology. Methods: Participants of the 2017 Rio de Janeiro Society of Cardiology Congress were interviewed. Knowledge about the World Health Organization (WHO) recommendations for fighting a sedentary lifestyle was assessed by asking participants the question: "How much weekly exercise is recommended by the WHO?" Responders were stratified by the weekly exercise load reported. A multivariate logistic model was created to determine independent predictors of knowledge. Results: A total of 426 participants were interviewed (45.5% men, median age 31 years, 37.8% physicians, 65.8% of the physicians were cardiologists). The overall knowledge level was 44.6%; 38.1%, 52.7% and 56.6% among non-physicians, non-cardiologists and cardiologists, respectively (p = 0.002). Of all participants, 21.8% were inactive, 15% were lightly active, 34.7% moderately active and 28.4% highly active, and the percentage of individuals who gave a correct answer to the question on exercise recommendations was 30.1%, 42%, 48% and 52.9% respectively (p < 0.0001). In the multivariate analysis, being highly active (OR = 2.25, IC95%, 1.238 - 4.089), moderately active (OR = 1.93, IC 95% 1.105 - 3.39) and being a cardiologist (OR = 2.01, IC 95% 1.243 - 3,267) were predictors of knowledge. Conclusions: There was a linear association between exercise level and knowledge about the WHO recommendations on exercise. Policies to stimulate the practice of exercise among health professionals can positively impact campaigns for reducing sedentary lifestyle in the general population

ABSTRACT

ABSTRACT Objective The objective of bladder augmentation (BA) is to create a low-pressure reservoir with adequate capacity. Despite its benefits, the use of intestinal patches in bladder enlargement provides a high risk of developing complications and BA with demucosalised bowel represents a potential alternative. Therefore, this study evaluated urological parameters and long-term clinical follow-up of patients submitted to non-secretory BA in a single center with 25 years of experience. Materials and Methods Patients treated with BA underwent urological evaluation, which included history, physical examination and urodynamic study. The main urodynamic parameters (bladder capacity and bladder compliance) were assessed in the pre and postoperative moments, and compared by the Wilcoxon Signed Rank test. The main long-term complications were described. Results 269 patients (mean age 14±13 years, 47% male) underwent BA with the use of demucolised intestinal segments. Among the patients in the sample, 187 (69.52%) had neurogenic bladder, 68 (25.28%) had bladder exstrophy, nine had tuberculosis (3.34%), four had a posterior urethral valve (1.49%) and one with hypospadia (0.37%). After the surgical procedure, a significant increment in both urodynamic parameters was found, with a 222% increase in bladder capacity and 604% in bladder compliance (p <0.001 in both analyzes). Mean follow-up time ranged from 2 to 358 months, with a median of 72 months (IQR 74-247). Among all patients, 5 presented spontaneous perforation. Conclusion The study showed statistically significant increase in both compliance and bladder capacity after non-secretory BA, with a low rate of severe complications.

ABSTRACT

Neste trabalho objetivou-se levantar e expor os preconceitos e a discriminação sofrida por idosas condutoras de veículos, analisando-os sob a ótica da psicologia do trânsito, neste país em que a feminização da velhice é uma tendência concreta. O preconceito engendrado na sociedade brasileira contra as condutoras de veículos é agravado pelo estereótipo negativo e a desvalorização que os idosos precisam enfrentar. Por isso, a condutora idosa sofre duplamente no trânsito, por ser mulher em uma sociedade machista, e por já se encontrar na velhice.


In this work it was intended to bring awareness and expose the prejudices and the discrimination faced by elderly female drivers, analyzing from the perspective of traffic psychology, in a country where the feminization of old age is a concrete trend. The prejudice that is rooted in the Brazilian society against the female drivers is aggravated by the negative stereotype and the devaluation that elderly people face. For this reason, the elderly female driver suffers twice as much in the traffic, first from being a woman in a misogynist society and second for being already in this phase of human development, which is growing old.


En este trabajo se objetivó levantar y exponer los prejuicios y la discriminación sufrida por ancianas conductoras de vehículos, analizándolos bajo la óptica de la psicología del tránsito, en un país donde la feminización de la vejez es una tendencia concreta. El preconcepto engendrado en la sociedad brasileña contra las conductoras de vehículos es agravado por el estereotipo negativo y la devaluación que enfrentan los ancianos. Por eso, la conductora anciana sufre doblemente en el tránsito, por ser mujer en una sociedad machista y por ya encontrarse en la fase del desarrollo humano, la vejez.

ABSTRACT

Introdução: Esta pesquisa tem como objetivo entender os fatores que determinam a escolha de um cirurgião plástico, na visão dos pacientes. É um projeto piloto que deve ser ampliado e aprofundado em outros estudos. Método: Foi idealizada uma pesquisa com 22 perguntas de múltipla escolha na forma de questionário. O tempo médio de resposta era de 8 minutos. As perguntas abordavam vários aspectos como a indicação/formação/titulação do cirurgião, percepção da primeira consulta e do consultório. Não havia possibilidade de identificação da paciente ou do cirurgião. O anonimato era garantido. Resultados: O índice de resposta foi de 86,66%. A maioria (92,22%) era do sexo feminino, com idade média de 35 anos. A maior parte tinha ensino médio e superior completos, com ganho familiar médio mensal de R$ 2 a 10 mil. Quase 40% não sabiam da titulação do cirurgião escolhido e 33,7% não sabia o tempo de formação do mesmo. A maioria (81,6%) acredita ter pago um valor na média pela sua cirurgia e metade não pesquisou a apresentação online do cirurgião. A maioria (67%) não tinha feito nenhuma cirurgia plástica previamente. Foi apresentada uma lista de 10 itens em ordem decrescente de importância. Conclusões: Os fatores determinantes para a escolha do cirurgião plástico nesta amostra, em ordem decrescente são: 1-Indicação, 2-Titulação e 3-Primeira consulta. Preço não está entre os primeiros atributos e apresentação online foi um dos últimos itens citados. Uma parte significativa dos pesquisados não conhece a titulação e nem o tempo de formação do seu cirurgião.


Introduction: This study aims to understand the factors that determine the choice of a plastic surgeon from the patient's perspective. This is a pilot project, which should be broadened and deepened by other studies. Method: A survey was devised in the form of a questionnaire with 22 multiple choice questions. The average response time was 8 minutes. The questions addressed various aspects, such as the recommendation, training, and accreditation of the surgeon; perception of the first consultation; and the clinic. There was no possibility of identifying the patient or surgeon; hence, anonymity was guaranteed. Results: The response rate was 86.66%. The majority (92.22%) of the respondents were female, with a mean age of 35 years. Most had completed secondary and higher education, with an average monthly family income of R$ 2,000 to 10,000. Almost 40% did not know the accreditation of the surgeon chosen and 33.7% did not know the length of training the surgeon had undergone. The majority (81.6%) believed they had paid an average amount for their surgery and half did not research the surgeon's online profile. The majority (67%) had not undergone any previous plastic surgery. A list of 10 items in descending order of importance was presented. Conclusions: The determining factors for the choice of the plastic surgeon in this sample, in descending order were: 1) Recommendation, 2) Accreditation, and 3) First consultation. Price was not the most important factor and online presence was one of the last items cited. A significant proportion of respondents did not know either the accreditation level or the length of training of their surgeon.

ABSTRACT

Objective: Comparing the costs and effectiveness of plasma genotyping versus tumor genotyping for detecting the T790M mutation in advanced non-small cell lung cancer (NSCLC) with a mutation in the epidermal growth factor receptor (EGFR) and that progressed after use of an EGFR tyrosine kinase inhibitor (EGFR-TKI), from the perspective of the private healthcare system in Brazil. Methods: Patients with a post-EGFR-TKI T790M mutation are eligible for a second-line treatment with a third-generation EGFR-TKI (osimertinib). In order to estimate the costs associated with the diagnosis method for the T790M mutation, a decision tree model has been used. Resource use was estimated by a team of experts, and the direct costs were estimated based on official databases. Results: Plasma genotyping provided a R$391 reduction per patient, due to the reduced cost with complications; it prevented 40.96% of the patients from undergoing an invasive procedure and 31.91% of the patients from having any kind of complication. Conclusion: Data found support a new paradigm for treating the resistance to EGFR-TKIs, with plasma genotyping as the first diagnostic choice, what can help to define the treatment and to reduce the costs of Brazilian private healthcare system.


Objetivo: Comparar os custos e efetividade da biópsia líquida versus biópsia tecidual para detecção da mutação T790M no câncer de pulmão de não pequenas células (CPNPC) avançado com mutação no receptor do fator de crescimento epidérmico (EGFR) e que progrediram após o uso de um inibidor do sítio da tirosina cinase associada ao EGFR (EGFR-TKI), sob a perspectiva do sistema suplementar de saúde do Brasil. Métodos: Pacientes com mutação EGFR-T790M pós-EGFR-TKI são elegíveis ao tratamento de segunda linha com um EGFR-TKI de terceira geração (osimertinibe). Para a estimativa dos custos relacionados ao método de diagnóstico de mutação T790M, foi elaborado um modelo de árvore de decisão. A utilização de recursos foi estimada por painel de especialistas e os custos diretos foram estimados utilizando-se bases de dados oficiais. Resultados: A biópsia líquida proporcionou redução de R$ 391 por paciente, devido a uma redução no custo com complicações; evitou que 40,96% dos pacientes passassem por um procedimento invasivo e que 31,95% dos pacientes tivessem algum tipo de complicação. Conclusão: Os dados observados embasam um novo paradigma para o manejo da resistência aos EGFR-TKIs, com genotipagem pelo plasma como primeira opção diagnóstica, o que pode auxiliar na melhor definição do tratamento e reduzir custos ao sistema de saúde suplementar brasileiro.
