ABSTRACT BACKGROUND: Hematopoietic stem cell transplantation (HSCT) recipients requiring intensive care unit (ICU) admission early after transplantation have a poor prognosis. However, many studies have only focused on allogeneic HSCT recipients. OBJECTIVES: To describe the characteristics of HSCT recipients admitted to the ICU shortly after transplantation and assess differences in 1-year mortality between autologous and allogeneic HSCT recipients. DESIGN AND SETTING: A single-center retrospective cohort study in a cancer center in Brazil. METHODS: We included all consecutive patients who underwent HSCT less than a year before ICU admission between 2009 and 2018. We collected clinical and demographic data and assessed the 1-year mortality of all patients. The effect of allogeneic HSCT compared with autologous HSCT on 1-year mortality risk was evaluated in an unadjusted model and an adjusted Cox proportional hazard model for age and Sequential Organ Failure Assessment (SOFA) at admission. RESULTS: Of the 942 patients who underwent HSCT during the study period, 83 (8.8%) were included in the study (autologous HSCT = 57 [68.7%], allogeneic HSCT = 26 [31.3%]). At 1 year after ICU admission, 21 (36.8%) and 18 (69.2%) patients who underwent autologous and allogeneic HSCT, respectively, had died. Allogeneic HSCT was associated with increased 1-year mortality (unadjusted hazard ratio, HR = 2.79 [confidence interval, CI, 95%, 1.48–5.26]; adjusted HR = 2.62 [CI 95%, 1.29–5.31]). CONCLUSION: Allogeneic HSCT recipients admitted to the ICU had higher short- and long-term mortality rates than autologous HSCT recipients, even after adjusting for age and severity at ICU admission.

ABSTRACT The number of patients with cancer requiring intensive care unit admission is increasing around the world. The improvement in the pathophysiological understanding of this group of patients, as well as the increasingly better and more targeted treatment options for their underlying disease, has led to a significant increase in their survival over the past three decades. Within the organizational concepts, it is necessary to know what adds value in the care of critical oncohematological patients. Practices in medicine that do not benefit patients and possibly cause harm are called low-value practices, while high-value practices are defined as high-quality care at relatively low cost. In this article, we discuss ten domains with high-value evidence in the care of cancer patients: (1) intensive care unit admission policies; (2) intensive care unit organization; (3) etiological investigation of hypoxemia; (4) management of acute respiratory failure; (5) management of febrile neutropenia; (6) urgent chemotherapy treatment in critically ill patients; (7) patient and family experience; (8) palliative care; (9) care of intensive care unit staff; and (10) long-term impact of critical disease on the cancer population. The disclosure of such policies is expected to have the potential to change health care standards. We understand that it is a lengthy process, and initiatives such as this paper are one of the first steps in raising awareness and beginning a discussion about high-value care in various health scenarios.

RESUMO O número de pacientes oncológicos com necessidade de internação em unidades de terapia intensiva está aumentando em todo o mundo. A maior compreensão fisiopatológica desse grupo de pacientes, bem como opções de tratamento cada vez melhores e mais direcionadas à doença subjacente, tem levado a um aumento significativo da sobrevida nas últimas três décadas. Dentro dos conceitos organizacionais é necessário saber o que agrega valor ao cuidado de pacientes onco-hematológicos graves. As práticas terapêuticas não benéficas aos pacientes e possivelmente causadoras de danos são chamadas práticas de baixo valor, enquanto as práticas de alto valor são definidas como cuidados de alta qualidade a um custo relativamente baixo. Neste artigo discutimos dez domínios com evidências de alto valor no cuidado de pacientes com câncer: (1) políticas de internação na unidade de terapia intensiva; (2) organização da unidade de terapia intensiva; (3) investigação etiológica da hipoxemia; (4) manejo da insuficiência respiratória aguda; (5) manejo da neutropenia febril; (6) tratamento quimioterápico de urgência em pacientes graves; (7) experiência do paciente e da família; (8) cuidados paliativos; (9) cuidados com a equipe da unidade de terapia intensiva; e (10) impacto a longo prazo da doença grave na população oncológica. Esperase que a divulgação dessas políticas traga mudanças aos padrões atuais do cuidado em saúde. Entendemos que é um processo longo, e iniciativas como o presente artigo são um dos primeiros passos para aumentar a conscientização e possibilitar discussão sobre cuidados de alto valor em vários cenários de saúde.

ABSTRACT Objective To describe the epidemiological aspects of COVID-19 in patients with prostate cancer who received androgen deprivation therapy and those who did not. Methods We retrospectively analyzed the medical records of patients with prostate cancer undergoing androgen deprivation therapy and those who did not undergo androgen deprivation therapy. These patients were treated at the A.C.Camargo Cancer Center between March 2020 and March 2021. Results Of the 78 patients with prostate cancer and positive RT-PCR test results, 50% were undergoing androgen deprivation therapy, and 49% were experiencing a non-metastatic biochemical relapse. Of these, 80.6% were symptomatic on the day of examination compared to 97.2% in the Control Group. A total of 82.1% of the patients receiving androgen deprivation therapy required hospitalization, with 30.8% admitted to the intensive care unit compared to 21.6% in the Control Group. There was no statistically significant difference in the use of a high-flow oxygen cannula, the need for orotracheal intubation and mechanical ventilation, the need for dialysis, multiple organ failure, or death. A significant difference was found between the groups in terms of the average length of stay in the intensive care unit. Conclusion Androgen deprivation therapy was not associated with protective factors or potential treatments in patients with prostate cancer and COVID-19. Although the number of patients analyzed was limited, and there may have been a selection bias, this is a unique study that cannot be expanded or replicated in similar (unvaccinated) populations.

RESUMO Objetivo: Avaliar como a funcionalidade e a disfunção orgânica aguda influenciam a mortalidade hospitalar de pacientes oncológicos admitidos com suspeita de sepse. Métodos: Os dados foram obtidos de uma coorte retrospectiva de pacientes oncológicos com suspeita de infecção admitidos em uma unidade de terapia intensiva. Estes receberam antibióticos por via parenteral e tiveram suas culturas coletadas. Utilizamos uma regressão logística, para avaliar a mortalidade hospitalar como desfecho, Sequential Organ Failure Assessment e Eastern Cooperative Oncology Group como preditores, além de suas interações. Resultados: Dentre os 450 pacientes incluídos, 265 (58,9%) morreram no hospital. Para os pacientes admitidos na unidade de terapia intensiva com Sequential Organ Failure Assessment baixo (≤ 6), o comprometimento da funcionalidade influenciou a mortalidade hospitalar, que foi de 32% entre os pacientes sem comprometimento ou com comprometimento mínimo da funcionalidade e 52% entre os pacientes com comprometimento moderado e grave (p < 0,01). Nos pacientes com Sequential Organ Failure Assessment elevado (> 6), a funcionalidade não influenciou a mortalidade hospitalar (73% entre os pacientes sem comprometimento ou com comprometimento mínimo, e 84% entre os pacientes com comprometimento moderado e grave; p = 0,1). Conclusão: O comprometimento da funcionalidade parece influenciar a mortalidade hospitalar de pacientes oncológicos com suspeita de sepse sem disfunções orgânicas agudas ou que apresentem disfunções leves no momento da admissão na unidade de terapia intensiva.

ABSTRACT Objective: To evaluate how performance status impairment and acute organ dysfunction influence hospital mortality in critically ill patients with cancer who were admitted with suspected sepsis. Methods: Data were obtained from a retrospective cohort of patients, admitted to an intensive care unit, with cancer and with a suspected infection who received parenteral antibiotics and underwent the collection of bodily fluid samples. We used logistic regression with hospital mortality as the outcome and the Sequential Organ Failure Assessment score, Eastern Cooperative Oncology Group status, and their interactions as predictors. Results: Of 450 patients included, 265 (58.9%) died in the hospital. For patients admitted to the intensive care unit with lower Sequential Organ Failure Assessment (≤ 6), performance status impairment influenced the in-hospital mortality, which was 32% among those with no and minor performance status impairment and 52% among those with moderate and severe performance status impairment, p < 0.01. However, for those with higher Sequential Organ Failure Assessment (> 6), performance status impairment did not influence the in-hospital mortality (73% among those with no and minor impairment and 84% among those with moderate and severe impairment; p = 0.1). Conclusion: Performance status impairment seems to influence hospital mortality in critically ill cancer patients with suspected sepsis when they have less severe acute organ dysfunction at the time of intensive care unit admission.

RESUMO Objetivo: Avaliar a frequência de visitas multidisciplinares durante a estadia na unidade de terapia intensiva e a participação dos diferentes profissionais da unidade, identificar as razões pelas quais as visitas não foram realizadas em dias específicos e se a taxa de ocupação e a carga de trabalho da enfermagem estavam associadas com a realização de visitas multidisciplinares. Métodos: Realizamos um estudo transversal para avaliar a frequência de visitas multidisciplinares em quatro unidades de terapia intensiva localizadas em um centro para tratamento de câncer. Colhemos também dados referentes à participação de profissionais, a razões para não realização das visitas nos casos em que elas não ocorriam e a taxas diárias de ocupação de leitos, assim como avaliamos a carga de trabalho da enfermagem por meio do Nursing Activity Score. Resultados: Foram conduzidas visitas multidisciplinares em 595 (65,8%) dos 889 dias de unidade de terapia intensiva avaliados. Mais frequentemente tomaram parte dessas visitas enfermeiros, médicos, fisioterapeutas respiratórios e profissionais ligados ao controle de infecções. As visitas não ocorreram em razão da admissão de novos pacientes no horário programado para a visita (136; 44,7%) e do envolvimento dos enfermeiros em atividades não relacionadas ao cuidado de pacientes (97; 31,9%). Na análise multivariada, níveis mais elevados do Nursing Activity Score se associaram com maior tendência à realização de visitas multidisciplinares (RC = 1,06; IC95% 1,04 - 1,10; p < 0,01), enquanto as taxas de ocupação não tiveram essa associação (RC = 0,99; IC95% 0,97 - 1,00; p = 0,18). Conclusão: Realizaram-se visitas multidisciplinares em menos de dois terços dos dias de unidade de terapia intensiva pesquisados. Muitas das visitas foram canceladas em razão de atividades não relacionadas aos cuidados com o paciente. A carga de trabalho é um possível gatilho para discussão dos alvos do dia para melhorar os desfechos dos pacientes e incrementar a efetividade das equipes multidisciplinares.

Abstract Objective: To assess the frequency of multidisciplinary rounds during ICU days, to evaluate the participation of diverse healthcare professionals, to identify the reasons why rounds were not performed on specific days, and whether bed occupancy rate and nurse workload were associated with the conduction of multidisciplinary rounds. Methods: We performed a cross-sectional study to assess the frequency of multidisciplinary rounds in four intensive care units in a cancer center. We also collected data on rates of professional participation, reasons for not performing rounds when they did not occur, and daily bed occupancy rates and assessed nurse workload by measuring the Nursing Activity Score. Results: Rounds were conducted on 595 (65.8%) of 889 surveyed intensive care unit days. Nurses, physicians, respiratory therapists, pharmacists, and infection control practitioners participated most often. Rounds did not occur due to admission of new patients at the scheduled time (136; 44.7%) and involvement of nurses in activities unrelated to patients’ care (97; 31.9%). In multivariate analysis, higher Nursing Activity Scores were associated with greater odds of conducting multidisciplinary rounds (OR = 1.06; 95%CI 1.04 - 1.10; p < 0.01), whereas bed occupancy rates were not (OR = 0.99; 95%CI 0.97 - 1.00; p = 0.18). Conclusion: Multidisciplinary rounds were conducted on less than two-thirds of surveyed intensive care unit days. Many rounds were cancelled due to activities unrelated to patient care. Unexpectedly, increased workload was associated with higher odds of conducting rounds. Workload is a possible trigger to discuss daily goals to improve patient outcomes and to enhance the effectiveness of multidisciplinary teams.

Abstract Humankind has always been fascinated by venomous animals, as their toxic substances have transformed them into symbols of power and mystery. Over the centuries, researchers have been trying to understand animal venoms, unveiling intricate mixtures of molecules and their biological effects. Among venomous animals, Latrodectus Walckenaer, 1805 (widow spiders) have become feared in many cultures worldwide due to their extremely neurotoxic venom. The Latrodectus genus encompasses 32 species broadly spread around the globe, 14 of which occur in the Americas. Despite the high number of species found in the New World, the knowledge on these spiders is still scarce. This review covers the general knowledge on Latrodectus spp. from the Americas. We address widow spiders’ taxonomy; geographical distribution and epidemiology; symptoms and treatments of envenomation (latrodectism); venom collection, experimental studies, proteome and transcriptome; and biotechnological studies on these Latrodectus spp. Moreover, we discuss the main challenges and limitations faced by researchers when trying to comprehend this neglected group of medically important spiders. We expect this review to help overcome the lack of information regarding widow spiders in the New World.

RESUMO Objetivo: Descrever a implantação de um serviço de telemedicina de UTI durante a pandemia de COVID-19, assim como descrever e analisar os resultados dos primeiros quatro meses de funcionamento do programa. Métodos: Estudo observacional descritivo da implantação de um serviço de telemedicina de UTI seguido de análise retrospectiva dos dados clínicos de pacientes com COVID-19 internados em UTI entre abril e julho de 2020. Resultados: O serviço foi implantado em quatro semanas e mostrou-se viável em meio à pandemia. O treinamento foi desenhado para ser remoto e baseado em evidências, promovendo a padronização do atendimento aos pacientes com COVID-19. Mais de 100.000 visualizações foram registradas nas plataformas on-line de acesso livre e no aplicativo móvel. Durante o período do estudo, os casos de 326 pacientes com COVID-19 foram avaliados no programa. A mediana de idade foi de 60 anos (variação: 49-68 anos). Houve predomínio do sexo masculino (56%) e alta prevalência de hipertensão arterial (49,1%) e diabetes mellitus (38,4%). Na admissão na UTI, 83,7% dos pacientes estavam em ventilação mecânica invasiva, com uma mediana da relação PaO2/FiO2 < 150. Ventilação pulmonar protetora foi possível em 75% dos casos. A mortalidade na UTI foi de 65%, e a mortalidade hospitalar foi de 68%. Conclusões: A telemedicina de UTI forneceu treinamento multidisciplinar aos profissionais de saúde e acompanhamento clínico de centenas de pacientes críticos. A iniciativa na rede pública foi pioneira e mostrou-se viável em meio à pandemia de COVID-19, incentivando a criação de projetos semelhantes que combinem práticas baseadas em evidências, treinamento e telemedicina.

ABSTRACT Objective: To describe the implementation of a Tele-ICU program during the COVID-19 pandemic, as well as to describe and analyze the results of the first four months of operation of the program. Methods: This was a descriptive observational study of the implementation of a Tele-ICU program, followed by a retrospective analysis of clinical data of patients with COVID-19 admitted to ICUs between April and July of 2020. Results: The Tele-ICU program was implemented over a four-week period and proved to be feasible during the pandemic. Participants were trained remotely, and the program had an evidence-based design, the objective being to standardize care for patients with COVID-19. More than 100,000 views were recorded on the free online platforms and the mobile application. During the study period, the cases of 326 patients with COVID-19 were evaluated through the program. The median age was 60 years (IQR, 49-68 years). There was a predominance of males (56%). There was also a high prevalence of hypertension (49.1%) and diabetes mellitus (38.4%). At ICU admission, 83.7% of patients were on invasive mechanical ventilation, with a median PaO2/FiO2 ratio < 150. It was possible to use lung-protective ventilation in 75% of the patients. Overall, in-hospital mortality was 68%, and ICU mortality was 65%. Conclusions: Our Tele-ICU program provided multidisciplinary training to health care professionals and clinical follow-up for hundreds of critically ill patients. This public health care network initiative was unprecedented and proved to be feasible during the COVID-19 pandemic, encouraging the creation of similar projects that combine evidence-based practices, training, and Tele-ICU.

RESUMO Objetivo: Mostrar o quadro clínico e os desfechos de uma coorte de pacientes críticos com câncer esofágico. Métodos: Conduzimos um estudo multicêntrico retrospectivo que incluiu pacientes com câncer esofágico admitidos a unidades de terapia intensiva em razão de doença aguda entre setembro de 2009 e dezembro de 2017. Colhemos os dados demográficos e as características clínicas de todos os pacientes incluídos, assim como as medidas de suporte a órgãos e os desfechos no hospital. Realizamos uma análise de regressão logística para identificar os fatores associados de forma independente com mortalidade hospitalar. Resultados: Dentre os 226 pacientes incluídos no estudo, 131 (58,0%) faleceram antes de receber alta hospitalar. O carcinoma espinocelular foi mais frequente do que o adenocarcinoma, e 124 (54,9%) pacientes tinham câncer metastático. As principais razões para admissão foram sepse/choque séptico e insuficiência respiratória aguda. Uso de ventilação mecânica (RC = 6,18; IC95% 2,86 - 13,35) e doença metastática (RC = 7,10; IC95% 3,35 - 15,05) tiveram associação independente com mortalidade hospitalar. Conclusão: Nesta coorte de pacientes com câncer esofágico admitidos à unidades de terapia intensiva em razão de doença aguda, a taxa de mortalidade hospitalar foi muito elevada. A necessidade de utilizar ventilação mecânica invasiva e a presença de doença metastática foram fatores independentes de prognóstico e devem ser levados em conta nas discussões a respeito dos desfechos destes pacientes em curto prazo.

ABSTRACT Objective: To depict the clinical presentation and outcomes of a cohort of critically ill patients with esophageal cancer. Methods: We carried out a multicenter retrospective study that included patients with esophageal cancer admitted to intensive care units with acute illness between September 2009 and December 2017. We collected the demographic and clinical characteristics of all included patients, as well as organ-support measures and hospital outcomes. We performed logistic regression analysis to identify independent factors associated with in-hospital mortality. Results: Of 226 patients included in the study, 131 (58.0%) patients died before hospital discharge. Squamous cell carcinoma was more frequent than adenocarcinoma, and 124 (54.9%) patients had metastatic cancer. The main reasons for admission were sepsis/septic shock and acute respiratory failure. Mechanical ventilation (OR = 6.18; 95%CI 2.86 - 13.35) and metastatic disease (OR = 7.10; 95%CI 3.35 - 15.05) were independently associated with in-hospital mortality. Conclusion: In this cohort of patients with esophageal cancer admitted to intensive care units with acute illness, the in-hospital mortality rate was very high. The requirement for invasive mechanical ventilation and metastatic disease were independent prognostic factors and should be considered in discussions about the short-term outcomes of these patients.

RESUMO O diafragma é o principal músculo da respiração e age de forma contínua e ininterrupta para mantê-la. Muitas patologias podem causar disfunção diafragmática, que é geralmente subdiagnosticada na prática clínica em virtude de sua apresentação inespecífica. Embora várias técnicas tenham sido usadas na avaliação da função diafragmática, o diagnóstico de disfunção diafragmática ainda é problemático. A ultrassonografia diafragmática ganhou importância em virtude de suas muitas vantagens: não é invasiva, não expõe os pacientes à radiação, está amplamente disponível, fornece resultados imediatos, é altamente precisa e é repetível à beira do leito. Vários autores descreveram técnicas ultrassonográficas para avaliar a excursão e o espessamento diafragmático na zona de aposição. Estudos recentes propuseram a padronização dos métodos. Este artigo de revisão analisa a utilidade da ultrassonografia na avaliação da função diafragmática, abordando os detalhes da técnica, os principais achados e as aplicações clínicas.

ABSTRACT The diaphragm is the main muscle of respiration, acting continuously and uninterruptedly to sustain the task of breathing. Diaphragmatic dysfunction can occur secondary to numerous pathological conditions and is usually underdiagnosed in clinical practice because of its nonspecific presentation. Although several techniques have been used in evaluating diaphragmatic function, the diagnosis of diaphragmatic dysfunction is still problematic. Diaphragmatic ultrasound has gained importance because of its many advantages, including the fact that it is noninvasive, does not expose patients to radiation, is widely available, provides immediate results, is highly accurate, and is repeatable at the bedside. Various authors have described ultrasound techniques to assess diaphragmatic excursion and diaphragm thickening in the zone of apposition. Recent studies have proposed standardization of the methods. This article reviews the usefulness of ultrasound for the evaluation of diaphragmatic function, addressing the details of the technique, the main findings, and the clinical applications.

RESUMO Objetivo: Desenvolver e aplicar um teste baseado em competências para avaliar o aprendizado de residentes de clínica médica em estágio na UTI respiratória de um hospital universitário. Métodos: Desenvolvemos um teste com 19 questões de múltipla escolha sobre conhecimento em ventilação mecânica (VM) e 4 questões de autoavaliação sobre o nível de confiança no manejo da VM. Os testes foram aplicados no primeiro (pré-estágio) e no último dia (pós-estágio) do estágio de 30 dias na UTI respiratória. Durante o estágio, os residentes tiveram aulas teóricas, treinamento com simulador e visitas diárias à beira do leito focadas no ensino de VM. Resultados: Cinquenta residentes completaram o teste nos dois momentos. A média de pontuação (0-10 pontos) aumentou de 6,9 ± 1,2 no pré-estágio para 8,6 ± 0,8 no pós-estágio (p < 0,001). Observamos um aumento significativo no pós-estágio comparado com o pré-estágio em questões sobre abordagem da hipoxemia, reconhecimento da assincronia paciente-ventilador e reconhecimento de fatores de risco para falha de extubação. A confiança na abordagem de vias aéreas aumentou de 6% para 22% ao final do estágio (p = 0,02). A confiança no ajuste inicial da VM subiu de 31% para 96% (p < 0,001), e a confiança no ajuste dos modos ventilatórios aumentou de 23% para 77% (p < 0,001). Conclusões: Desenvolvemos um teste baseado em competências para avaliar o conhecimento sobre VM entre residentes antes e depois de um estágio em UTI respiratória. O desempenho dos residentes ao final do estágio aumentou significativamente, assim como sua confiança para cuidar de pacientes sob VM.

ABSTRACT Objective: To develop and apply a competency-based test to assess learning among internal medicine residents during a respiratory ICU rotation at a university hospital. Methods: We developed a test comprising 19 multiple-choice questions regarding knowledge of mechanical ventilation (MV) and 4 self-assessment questions regarding the degree of confidence in the management of MV. The test was applied on the first and last day of a 30-day respiratory ICU rotation (pre-rotation and post-rotation, respectively). During the rotation, the residents had lectures, underwent simulator training, and shadowed physicians on daily bedside rounds focused on teaching MV management. Results: Fifty residents completed the test at both time points. The mean score increased from 6.9 ± 1.2 (pre-rotation) to 8.6 ± 0.8 (post-rotation; p < 0.001). On questions regarding the approach to hypoxemia, the recognition of patient-ventilator asynchrony, and the recognition of risk factors for extubation failure, the post-rotation scores were significantly higher than the pre-rotation scores. Confidence in airway management increased from 6% before the rotation to 22% after the rotation (p = 0.02), whereas confidence in making the initial MV settings increased from 31% to 96% (p < 0.001) and confidence in adjusting the ventilator modes increased from 23% to 77% (p < 0.001). Conclusions: We developed a competency-based test to assess knowledge of MV among residents before and after an rotation in a respiratory ICU. Resident performance increased significantly after the rotation, as did their confidence in caring for patients on MV.

RESUMO Este estudo apresenta o panorama do tratamento de doenças raras no Brasil, enfocando questões relacionadas à judicialização e ao Complexo Econômico-Industrial da Saúde. São analisadas as estruturas jurídicas e econômicas pertinentes ao tema, questionando a ausência de soluções nacionais articuladas, o que torna a judicialização para o tratamento de doenças raras a solução – ineficiente e insatisfatória, segundo se diz – para o cumprimento do dispositivo. Saúde como um direito. Nesse contexto, são debatidas estratégias para mitigar a dependência tecnológica e econômica, a fim de sustentar o acesso universal, integral e equitativo à saúde. Metodologicamente, a perspectiva do trabalho é primariamente teórica, exploratória e baseada em informações documentais e literatura acadêmica sobre o assunto, passando pelas normas administrativas, decisões judiciais e textos explicativos sobre o assunto em sua dimensão jurídica, econômica e institucional. Concluindo, percebe-se que os gastos com saúde podem comprometer uma parcela significativa do orçamento nacional, dada a importação de medicamentos e outros tratamentos. Portanto, a interação entre o judiciário e o poder executivo e seus órgãos técnicos executivos é mensurada com urgência para fornecer uma racionalidade sanitária e econômica ao sistema, para garantir acesso universal, equitativo e integral ao atendimento de doenças raras.

ABSTRACT This study presents the panorama of the treatment of rare diseases in Brazil, focusing on issues related to judicialization and the Health Economic-Industrial Complex. The legal and economic structures pertinent to the theme are analyzed, questioning the absence of articulated national solutions, which makes judicialization for the treatment of rare diseases the solution – inefficient and unsatisfactory, it is said – for complying with the device. Health as a right. In this context, strategies are debated to mitigate technological and economic dependence in order to sustain universal, integral, and equitable access to health. Methodologically, the perspective of the work is primarily theoretical, exploratory and based on documentary information and academic literature on the subject, going through the administrative rules, court decisions and explanatory texts on the subject in its legal, economic, and institutional dimension. In conclusion, it can be noticed that health spending can compromise a significant portion of the national budget, given the importation of medicines and other treatments. Therefore, the interaction between the Judiciary and the Executive branch and its technical executive bodies is urgently measured to provide a sanitary and economic rationality to the system, to ensure universal, equitable, and integral access to care for rare diseases.

RESUMO Objetivo: Avaliar o papel do posicionamento intrapleural do cateter pleural na expansão pulmonar precoce e no sucesso da pleurodese em pacientes com derrame pleural maligno recorrente (DPMR). Métodos: Trata-se de um estudo retrospectivo aninhado em um estudo prospectivo de coorte maior com pacientes com DPMR recrutados em um hospital-escola universitário terciário entre junho de 2009 e setembro de 2014. Os pacientes foram submetidos a inserção de cateter pleural e, em seguida, pleurodese à beira do leito. A TC de tórax foi realizada duas vezes: imediatamente antes da pleurodese (TCi) e 30 dias após a pleurodese (TC30). Com base na TCi, a posição do cateter foi classificada em posterolateral, anterior, fissural e subpulmonar. Usamos o volume pleural na TCi para estimar a expansão pulmonar precoce e a diferença entre os volumes pleurais na TC30 e na TCi a fim de avaliar o sucesso radiológico da pleurodese. Considerou-se que a pleurodese teve êxito clínico quando não foi necessário realizar nenhum outro procedimento pleural. Resultados: Dos 131 pacientes elegíveis do estudo original, 85 foram incluídos neste estudo aninhado (64 mulheres; média de idade: 60,74 anos). A posição da ponta do cateter foi subpulmonar em 35 pacientes (41%), anterior em 23 (27%), posterolateral em 17 (20%) e fissural em 10 (12%). Não houve diferenças significativas entre os grupos quanto à expansão pulmonar precoce (mediana da cavidade pleural residual = 377 ml; intervalo interquartil: 171-722 ml; p = 0,645), sucesso radiológico da pleurodese (mediana do volume = 33 ml; intervalo interquartil: −225 a 257 ml; p = 0,923) e sucesso clínico da pleurodese (85,8%; p = 0,676). Conclusões: Nossos resultados sugerem que a posição da ponta do cateter pleural não influencia nem a expansão pulmonar precoce nem o sucesso da pleurodese à beira do leito em pacientes com DPMR.

ABSTRACT Objective: To evaluate the role of intrapleural positioning of a pleural catheter in early lung expansion and pleurodesis success in patients with recurrent malignant pleural effusion (RMPE). Methods: This was a retrospective study nested into a larger prospective cohort study including patients with RMPE recruited from a tertiary university teaching hospital between June of 2009 and September of 2014. The patients underwent pleural catheter insertion followed by bedside pleurodesis. Chest CT scans were performed twice: immediately before pleurodesis (iCT) and 30 days after pleurodesis (CT30). Catheter positioning was categorized based on iCT scans as posterolateral, anterior, fissural, and subpulmonary. We used the pleural volume on iCT scans to estimate early lung expansion and the difference between the pleural volumes on CT30 and iCT scans to evaluate radiological success of pleurodesis. Clinical pleurodesis success was defined as no need for any other pleural procedure. Results: Of the 131 eligible patients from the original study, 85 were included in this nested study (64 women; mean age: 60.74 years). Catheter tip positioning was subpulmonary in 35 patients (41%), anterior in 23 (27%), posterolateral in 17 (20%), and fissural in 10 (12%). No significant differences were found among the groups regarding early lung expansion (median residual pleural cavity = 377 mL; interquartile range: 171-722 mL; p = 0.645), radiological success of pleurodesis (median volume = 33 mL; interquartile range: −225 to 257 mL; p = 0.923), and clinical success of pleurodesis (85.8%; p = 0.676). Conclusions: Our results suggest that the position of the tip of the pleural catheter influences neither early lung expansion nor bedside pleurodesis success in patients with RMPE.
