ABSTRACT

Abstract Objective: To investigate the clinical and swallowing indicators related to a successful decannulation process during the hospital stay. Methods: A retrospective cohort clinical study. The study sample comprised a heterogeneous patient population who had submitted to a tracheostomy procedure in a tertiary hospital. Patients were divided into two groups (dec-annulated vs. non-decannulated) and compared not only in terms of demographic and clinical data but also the results of a swallowing assessment and intervention outcome. Results: Sixty-four patients were included in the present study: 25 (39%) who had been successfully decannulated, and 39 (61%) who could not be decannulated. Between-group comparisons indicated that both groups presented similar clinical and demographic characteristics. The groups also presented similar swallowing assessment results prior to intervention. However, significant differences were observed regarding the time to begin swallowing rehabilitation. The decannulated group was assessed nine days earlier than the non-decannulated group. Other significant differences included the removal of the alternate feeding method (72.0% of decannulated patients vs. 5.1% of non-decannulated patients) and the reintroduction of oral feeding (96.0% of decannulated patients vs. 41.0% of non-decannulated patients) and functional swallowing level at patient disclosure. The non-decannulated patient group presented higher death rates at disclosure. Conclusion: The results of the present study indicated that the following parameters were associated with a successful decannulation process: early swallowing assessment, swallowing rehabilitation, and improvement in the swallowing functional level during the hospital stay. The maintenance of low swallowing functional levels was found to be negatively associated with successful decannulation. HIGHLIGHTS Deccanulation indicators were investigated in patients who were submitted to a tracheostomy procedure. Early swallowing evaluation and rehabilitation were associated with a successful decannulation process. Low swallowing functional levels were negatively associated with the success of decannulation.

ABSTRACT

RESUMO Objetivo: Avaliar a capacidade do Teste de Caminhada de 6 Minutos para predizer a melhora do estado funcional físico em longo prazo de pacientes sobreviventes à unidade de terapia intensiva. Métodos: Foram avaliados, de forma prospectiva, entre fevereiro de 2017 e agosto de 2018, em um ambulatório pós-unidade de terapia intensiva, 32 sobreviventes à unidade de terapia intensiva. Foram inscritos consecutivamente os pacientes com permanência na unidade de terapia intensiva acima de 72 horas (para admissões emergenciais) ou acima de 120 horas (para admissões eletivas) que compareceram ao ambulatório pós-unidade de terapia intensiva 4 meses após receberem alta da unidade de terapia intensiva. A associação entre a distância percorrida no Teste de Caminhada de 6 Minutos realizado na avaliação inicial e a evolução do estado funcional físico foi avaliada durante 8 meses, com utilização do Índice de Barthel. Resultados: A distância média percorrida no Teste de Caminhada de 6 Minutos foi significantemente mais baixa nos sobreviventes à unidade de terapia intensiva do que na população geral (405m versus 557m; p < 0,001). A idade (β = -4,0; p < 0,001) e a fraqueza muscular (β = -99,7; p = 0,02) se associaram com a distância percorrida no Teste de Caminhada de 6 Minutos. A distância percorrida no Teste de Caminhada de 6 Minutos se associou com melhora do estado funcional físico no período de 8 meses de acompanhamento desses pacientes (razão de chance para cada 10m: 1,07; IC95% 1,01 - 1,16; p = 0,03). A área sob a curva Característica de Operação do Receptor para predição da melhora funcional física pelo Teste de Caminhada de 6 Minutos foi de 0,72 (IC95% 0,53 - 0,88). Conclusão: O Teste de Caminhada de 6 Minutos, realizado 4 meses após a alta da unidade de terapia intensiva, predisse com precisão moderada a melhora do estado funcional físico de sobreviventes à unidade de terapia intensiva.


ABSTRACT Objective: To evaluate the ability of the 6-Minute Walk Test to predict long-term physical functional status improvement among intensive care unit survivors. Methods: Thirty-two intensive care unit survivors were prospectively evaluated from February 2017 to August 2018 in a post-intensive care unit outpatient clinic in Brazil. Individuals with intensive care unit stays > 72 hours (emergency admissions) or > 120 hours (elective admissions) attending the post-intensive care unit clinic four months after intensive care unit discharge were consecutively enrolled. The association between the 6-Minute Walk Test distance at baseline and physical functional status was assessed over 8 months using the Barthel Index. Results: The mean 6-Minute Walk Test distance was significantly lower in intensive care unit survivors than in the general population (405m versus 557m; p < 0.001). Age (β = -4.0; p < 0.001) and muscle weakness (β = -99.7; p = 0.02) were associated with the 6-Minute Walk Test distance. A 6-Minute Walk Test distance was associated with improvement in physical functional status over the 8-month follow-up (odds ratio for each 10m of 1.07; 95%CI 1.01 - 1.16; p = 0.03). The area under the Receiver Operating Characteristic curve for the 6-Minute Walk Test prediction of physical functional status improvement was 0.72 (95%CI 0.53 - 0.88). Conclusion: The 6-Minute Walk Test performed 4 months after intensive care unit discharge predicted long-term physical functional status among intensive care unit survivors with moderate accuracy.

ABSTRACT

RESUMO A melhoria da qualidade da ressuscitação cardiopulmonar vem reduzindo a mortalidade dos indivíduos atendidos em parada cardiorrespiratória. Porém, os sobreviventes apresentam risco elevado de dano cerebral grave em caso de retorno à circulação espontânea. Dados sugerem que paradas cardiorrespiratórias, que ocorram em pacientes criticamente doentes com ritmos cardíacos não chocáveis, apresentem somente 6% de chance de retorno à circulação espontânea e, destes, somente um terço consiga recuperar sua autonomia. Optaríamos, assim, pela realização de um procedimento em que a chance de sobrevida é mínima, e os sobreviventes apresentam risco de aproximadamente 70% de morte hospitalar ou dano cerebral grave e definitivo? Valeria a pena discutir se este paciente é ou não ressuscitável, em caso de parada cardiorrespiratória? Esta discussão traria algum benefício ao paciente e a seus familiares? As discussões avançadas de não ressuscitação se baseiam no princípio ético do respeito pela autonomia do paciente, pois o desejo dos familiares e dos médicos, muitas vezes, não se correlaciona adequadamente aos dos pacientes. Não somente pela ótica da autonomia, as discussões avançadas podem ajudar a equipe médica e assistencial a anteciparem problemas futuros, fazendo-os planejar melhor o cuidado dos enfermos. Ou seja, nossa opinião é a de que discussões sobre ressuscitação ou não dos pacientes criticamente doentes devam ser realizadas em todos os casos internados na unidade de terapia intensiva logo nas primeiras 24 a 48 horas de internação.


Abstract The improvement in cardiopulmonary resuscitation quality has reduced the mortality of individuals treated for cardiac arrest. However, survivors have a high risk of severe brain damage in cases of return of spontaneous circulation. Data suggest that cases of cardiac arrest in critically ill patients with non-shockable rhythms have only a 6% chance of returning of spontaneous circulation, and of these, only one-third recover their autonomy. Should we, therefore, opt for a procedure in which the chance of survival is minimal and the risk of hospital death or severe and definitive brain damage is approximately 70%? Is it worth discussing patient resuscitation in cases of cardiac arrest? Would this discussion bring any benefit to the patients and their family members? Advanced discussions on do-not-resuscitate are based on the ethical principle of respect for patient autonomy, as the wishes of family members and physicians often do not match those of patients. In addition to the issue of autonomy, advanced discussions can help the medical and care team anticipate future problems and, thus, better plan patient care. Our opinion is that discussions regarding the resuscitation of critically ill patients should be performed for all patients within the first 24 to 48 hours after admission to the intensive care unit.

ABSTRACT

Resumo As Unidades Básicas de Saúde (UBS) devem considerar o perfil demográfico e epidemiológico de sua região de saúde para se adequar ao envelhecimento populacional e se estruturar em redes, cujas bases estão na macro e microgestão, com vistas à integralidade da atenção. Foi conduzida avaliação normativa da microgestão de quatro UBS de uma Região de Saúde do Distrito Federal (DF) para posterior proposta de melhorias para ações voltadas a idosos. Utilizou-se matriz de avaliação da gestão, cuja classificação resultou em: avançada, intermediária e incipiente. Os resultados mostraram que nenhuma UBS está em estágio Avançado, três em Intermediário e uma Incipiente. Menores pontuações foram quanto ao Modelo de Atenção (maiormente tradicional) e à Humanização (com fragmentação do cuidado). Estrutura física deficitária e absenteísmo de profissionais foram dificultadores. Comunicação efetiva com gestão local foram identificadas como facilitadores. As UBS necessitam de avanços na microgestão para a qualificação do cuidado ofertado, principalmente quanto à implementação de modelo de atenção cuja integralidade seja atingida, de modo a ser garantido acesso oportuno e resolutivo para a população idosa nesta região de saúde.


Abstract Primary health centers (PHCs) should consider the demographic and epidemiological profile of the health region to respond to population aging and structure service delivery around networks based on macro and micro-level management to ensure the provision of comprehensive services. A normative evaluation of micro-level management in four PHCs in a health region in the Federal District of Brazil was conducted to inform the development of recommendations for enhancing the delivery of comprehensive and integrated long-term care for older persons. A management evaluation matrix was used where management stages were classified as advanced, intermediate and incipient. The findings show that none of the PHCs were at the advanced stage, three were at the intermediate stage, and one at the incipient stage. The lowest scores were obtained for the subdimensions care model (which was shown to be predominantly traditional) and humanization (fragmentation of care). Lack of infrastructure and staff absenteeism were shown to be constraining factors, while effective communication with local administrators was as facilitating factor. Improvements need to be made in micro-level management to enhance the delivery of comprehensive and timely care to older persons in this health region.

ABSTRACT

Neste artigo analisa-se o contributo das práticas de desenvolvimento vocacional e de aconselhamento de carreira para a inclusão e a justiça social. A abordagem é justificada pelo actual contexto de economia globalizada onde a rapidez da mudança tem levado à abertura de novas oportunidades, mas também tem colocado desafios à igualdade de oportunidades e à justiça social. Começa-se por situar historicamente o papel das práticas de desenvolvimento vocacional e de aconselhamento de carreira na promoção da justiça social. Depois, sublinha-se a necessidade destas práticas com populações desfavorecidas, equilibrando o foco no individuo com o foco nos fatores de discriminação e opressão. Por fim, apresenta-se um exemplo destas práticas onde a acção colaborativa é fundamental para facilitar a integração socioprofissional dessas populações.


This article addresses the contribution of career orientation and counseling to social inclusion and social justice. The approach is justified by the context of the current economic globalization, where rapid changes have led to new employment opportunities. However, they have also posed challenges related to equality and social justice. The role of professional orientation and counseling in the promotion of social justice is historically based. Thus, the need for practices, balancing both the focus on the individual and on discrimination, and oppression factors is highlighted for interventions in disadvantaged populations. Finally, we present several examples of these practices in which the collaboration between the target population, the family and different institutions of the community is central to the integration in the labor market.

El enfoque está justificado por el contexto de la globalización económica actual, en el que la rapidez de los cambios ha conducido a nuevas posibilidades, pero también ha supuesto retos relacionados con la igualdad de oportunidades y la justicia social. Se comienza situando históricamente el papel de las prácticas de desarrollo vocacional y de consejería de carrera en la promoción de la justicia social. Luego, se destaca la necesidad de estas prácticas con poblaciones desfavorecidas, equilibrando el enfoque en el individuo y en los factores de discriminación y opresión. Por último, se presenta un ejemplo de estas prácticas en el cual la acción colaborativa es fundamental para facilitar la integración socio-profesional de estas poblaciones.

ABSTRACT

ABSTRACT Objective: Conventional bronchoscopy has a low diagnostic yield for peripheral pulmonary lesions. Radial-probe EBUS employs a rotating ultrasound transducer at the end of a probe that is passed through the working channel of the bronchoscope. Radial-probe EBUS facilitates the localization of peripheral pulmonary nodules, thus increasing the diagnostic yield. The objective of this study was to present our initial experience using radial-probe EBUS in the diagnosis of peripheral pulmonary lesions at a tertiary hospital. Methods: We conducted a retrospective analysis of 54 patients who underwent radial-probe EBUS-guided bronchoscopy for the investigation of pulmonary nodules or masses between February of 2012 and September of 2013. Radial-probe EBUS was performed with a flexible 20-MHz probe, which was passed through the working channel of the bronchoscope and advanced through the bronchus to the target lesion. For localization of the lesion and for collection procedures (bronchial brushing, transbronchial needle aspiration, and transbronchial biopsy), we used fluoroscopy. Results: Radial-probe EBUS identified 39 nodules (mean diameter, 1.9 ± 0.7 cm) and 19 masses (mean diameter, 4.1 ± 0.9 cm). The overall sensitivity of the method was 66.7% (79.5% and 25.0%, respectively, for lesions that were visible and not visible by radial-probe EBUS). Among the lesions that were visible by radial-probe EBUS, the sensitivity was 91.7% for masses and 74.1% for nodules. The complications were pneumothorax (in 3.7%) and bronchial bleeding, which was controlled bronchoscopically (in 9.3%). Conclusions: Radial-probe EBUS shows a good safety profile, a low complication rate, and high sensitivity for the diagnosis of peripheral pulmonary lesions.


RESUMO Objetivo: A broncoscopia convencional possui baixo rendimento diagnóstico para lesões pulmonares periféricas. A ecobroncoscopia radial (EBUS radial) emprega um transdutor ultrassonográfico rotatório na extremidade de uma sonda que é inserida no canal de trabalho do broncoscópio. O EBUS radial facilita a localização de nódulos pulmonares periféricos, aumentando assim o rendimento diagnóstico. O objetivo deste estudo foi apresentar nossa experiência inicial com o uso de EBUS radial para o diagnóstico de lesões pulmonares periféricas em um hospital terciário. Métodos: Foi realizada uma análise retrospectiva de 54 pacientes submetidos à broncoscopia guiada por EBUS radial para a investigação de nódulos ou massas pulmonares entre fevereiro de 2012 e setembro de 2013. O EBUS radial foi realizado com uma sonda flexível de 20 MHz, que foi inserida no canal de trabalho do broncoscópio até chegar à lesão-alvo. A fluoroscopia foi usada para localizar a lesão e realizar procedimentos de coleta (escovado brônquico, aspiração transbrônquica com agulha e biópsia transbrônquica). Resultados: O EBUS radial identificou 39 nódulos (média de diâmetro: 1,9 ± 0,7 cm) e 19 massas (média de diâmetro: 4,1 ± 0,9 cm). A sensibilidade global do EBUS radial foi de 66,7% (79,5% para as lesões visíveis pelo método e 25% para as lesões não visíveis pelo método). Nas lesões visíveis pelo método, a sensibilidade foi de 91,7% para massas e de 74,1% para nódulos. As complicações foram pneumotórax (3,7%) e sangramento brônquico controlado broncoscopicamente (9,3%). Conclusões: O EBUS radial apresenta bom perfil de segurança, baixo índice de complicações e alta sensibilidade para o diagnóstico de lesões pulmonares periféricas.

ABSTRACT

Gravidez tardia é a gestação que ocorre na faixa etária de 35 anos ou mais. O apoio social é um processo dinâmico e complexo que envolve transações entre indivíduos e suas redes sociais. O objetivo geral foi averiguar possíveis relações entre o apoio social e variáveis sociodemográficas e gestacionais em gestantes tardias. A pesquisa é considerada descritiva e correlacional e de corte transversal, foi realizada com 150 gestantes tardias em Unidades Básicas de Saúde. Os instrumentos utilizados foram: Questionário Estruturado (dados sociodemográficos e gestacionais) e a Escala de Apoio Social. A maioria das gestantes apresentou baixa renda e escolaridade, tinha em média 37,5 anos de idade (DP = 2,6), além de não ter planejado a gravidez (60,7%). Prevaleceram indicadores elevados de apoio social global, material, emocional, afetivo, de informação e de interação social positiva. E nenhuma das variáveis sociodemográficas e gestacionais apresentaram correlações estatisticamente significativas com o apoio social global


Late-age pregnancy is gestation that occurs around age 35 or older. A social support is a dynamic and complex process involving interactions between individuals and their social networks. The general aim of this research was to investigate possible relationships between social support and socio-demographic and gestational variables in late-age pregnants. Cross-sectional co-relational and descriptive research was conducted with 150 late-age pregnant women in Basic Health Units. The instruments used were: Structured Questionnaire (demographic and gestational data) and the Scale of Social Support. Most of the interviewed women had low income and education, were in average 37,5 (±2,6) years, had not planned the pregnancy (60.7%). High indicators of global social support, material, emotional, affective, information and positive social interaction prevailed. And none of the socio-demographic and gestational variables showed statistically significant correlations with the global social support

ABSTRACT

Objective: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a minimally invasive, safe and accurate method for collecting samples from mediastinal and hilar lymph nodes. This study focused on the initial results obtained with EBUS-TBNA for lung cancer and lymph node staging at three teaching hospitals in Brazil. Methods: This was a retrospective analysis of patients diagnosed with lung cancer and submitted to EBUS-TBNA for mediastinal lymph node staging. The EBUS-TBNA procedures, which involved the use of an EBUS scope, an ultrasound processor, and a compatible, disposable 22 G needle, were performed while the patients were under general anesthesia. Results: Between January of 2011 and January of 2014, 149 patients underwent EBUS-TBNA for lymph node staging. The mean age was 66 ± 12 years, and 58% were male. A total of 407 lymph nodes were sampled by EBUS-TBNA. The most common types of lung neoplasm were adenocarcinoma (in 67%) and squamous cell carcinoma (in 24%). For lung cancer staging, EBUS-TBNA was found to have a sensitivity of 96%, a specificity of 100%, and a negative predictive value of 85%. Conclusions: We found EBUS-TBNA to be a safe and accurate method for lymph node staging in lung cancer patients. .


Objetivo: A endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA, punção aspirativa por agulha guiada por ultrassom endobrônquico) é um método seguro e preciso para a coleta de amostras de linfonodos mediastinais e hilares. O presente estudo teve por objetivo avaliar os resultados iniciais com EBUS-TBNA para o estadiamento linfonodal de câncer de pulmão em 3 hospitais acadêmicos no Brasil. Métodos: Análise retrospectiva de pacientes com neoplasia de pulmão diagnosticada e submetidos a EBUS-TBNA para estadiamento linfonodal mediastinal. Todos os procedimentos foram realizados sob anestesia geral. Utilizou-se um ecobroncoscópio, uma processadora de ultrassom e agulhas 22 G descartáveis e compatíveis com o ecobroncoscópio. Resultados: Entre janeiro de 2011 e janeiro de 2014, 149 pacientes foram submetidos ao estadiamento linfonodal com EBUS-TBNA. A média de idade foi 66 ± 12 anos, sendo 58% do sexo masculino. Um total de 407 linfonodos foram puncionados via EBUS-TBNA. Os tipos mais comuns de neoplasia brônquica foram adenocarcinoma (em 67%) e carcinoma escamoso (em 24%). Para o estadiamento da neoplasia, o EBUS-TBNA apresentou sensibilidade de 96%, especificidade de 100% e valor preditivo negativo de 85%. Conclusões: A EBUS-TBNA mostrou-se um método seguro e acurado no estadiamento linfonodal em pacientes com câncer de pulmão. .

ABSTRACT

Objective: To determine the effects of acute and chronic administration of methylprednisolone on oxidative stress, as quantified by measuring lipid peroxidation (LPO) and total reactive antioxidant potential (TRAP), in rat lungs. Methods: Forty Wistar rats were divided into four groups: acute treatment, comprising rats receiving a single injection of methylprednisolone (50 mg/kg i.p.); acute control, comprising rats i.p. injected with saline; chronic treatment, comprising rats receiving methylprednisolone in drinking water (6 mg/kg per day for 30 days); and chronic control, comprising rats receiving normal drinking water. Results: The levels of TRAP were significantly higher in the acute treatment group rats than in the acute control rats, suggesting an improvement in the pulmonary defenses of the former. The levels of lung LPO were significantly higher in the chronic treatment group rats than in the chronic control rats, indicating oxidative damage in the lung tissue of the former. Conclusions: Our results suggest that the acute use of corticosteroids is beneficial to lung tissue, whereas their chronic use is not. The chronic use of methylprednisolone appears to increase lung LPO levels. .


Objetivo: Determinar os efeitos da administração aguda e crônica de metilprednisolona no estresse oxidativo, por meio da quantificação da peroxidação lipídica (POL) e do potencial antioxidante reativo total (PART), em pulmões de ratos. Métodos: Quarenta ratos Wistar foram divididos em quatro grupos: tratamento agudo, com ratos recebendo uma dose única de metilprednisolona (50 mg/kg i.p.); controle agudo, com ratos recebendo injeção unida de salina; tratamento crônico, com ratos recebendo metilprednisolona v.o. na água do bebedouro (6 mg/kg por dia durante 30 dias; e controle crônico, com ratos recebendo água de bebedouro normal). Resultados: Os níveis de PART foram significativamente maiores no grupo tratamento agudo que no grupo controle agudo, sugerindo uma melhora do sistema de defesa pulmonar. Os níveis de POL foram significativamente maiores no grupo tratamento crônico que no grupo controle crônico, indicando dano oxidativo no tecido pulmonar. Conclusões: Nossos resultados sugerem que o uso agudo de corticoides foi benéfico aos tecidos pulmonares, enquanto seu uso crônico não o foi. O uso crônico de metilprednisolona parece aumentar os níveis pulmonares da POL. .

ABSTRACT

CONTEXT AND OBJECTIVE: Lung preservation remains a challenging issue for lung transplantation groups. Along with the development of ex vivo lung perfusion, a new preservation method known as topical-ECMO (extracorporal membrane oxygenation) has been proposed. The present study compared topical-ECMO with cold ischemia (CI) for lung preservation in an ex vivo experimental model. DESIGN AND SETTING: Randomized experimental study, conducted at a public medical school. METHOD: Fourteen human lungs were retrieved from seven brain-dead donors that were considered unsuitable for transplantation. The lung bloc was divided and each lung was randomized to be preserved by means of topical-ECMO or CI (4-7 °C) for eight hours. These lungs were then reconnected to an ex vivo perfusion system for functional evaluation. Lung biopsies were obtained at three times. The functional variables assessed were oxygenation capacity (OC) and pulmonary artery pressure (PAP); and the histological variables were lung injury score (LIS) and apoptotic cell count (ACC). RESULTS : The mean OC was 468 mmHg (± 81.6) in the topical-ECMO group and 455.8 (± 54) for CI (P = 0.758). The median PAP was 140 mmHg (120-160) in the topical-ECMO group and 140 mmHg (140-150) for CI (P = 0.285). The mean LIS was 35.57 (± 4.5) in the topical-ECMO group and 33.86 (± 6.1) for CI (P = 0.367). The ACC was 25.00 (± 9.34) in the topical-ECMO group and 24.86 (± 10.374) for CI (P = 0.803). CONCLUSIONS: The present study showed that topical-ECMO was not superior to cold ischemia for up to eight hours of lung preservation. .


CONTEXTO E OBJETIVO: A preservação pulmonar permanece um desafio para os grupos transplantadores. Com o desenvolvimento da perfusão pulmonar ex vivo, foi proposto um novo método de preservação chamado de ECMO-tópico (oxigenação de membrana extracorpórea). O presente estudo compara ECMO-tópico com isquemia fria (IF) para preservação pulmonar em um modelo experimental ex vivo. TIPO DE ESTUDO E LOCAL: Estudo experimental randomizado, conduzido em uma faculdade de medicina pública. MÉTODO: Quatorze pulmões humanos foram retirados de sete doadores de morte cerebral considerados não aptos a transplante. O bloco pulmonar foi dividido e cada um foi aleatorizado para preservação por ECMO-tópico ou IF (4-7 °C) durante oito horas. Esses pulmões foram então re-conectados a um sistema de perfusão ex vivo para avaliação funcional. Biópsias pulmonares foram obtidas em três tempos. As variáveis funcionais avaliadas foram: capacidade de oxigenação (CO) e pressão de artéria pulmonar (PAP). As variáveis histológicas estudadas foram escore de lesão pulmonar (ELP) e contagem de células apoptóticas (CCA). RESULTADOS: A média da CO foi de 468 mmHg (± 81.6) no grupo ECMO-tópico e 455.8 (± 54) no grupo IF (P = 0,758); a PAP média foi de 140 mmHg (120-160) para ECMO-tópico e 140 mmHg (140-150) para IF (P = 0,285); o ELP médio foi 35,57 (± 4,5) no ECMO-tópico e 33,86 (± 6,1) no IF (P = 0,367). A CCA foi 25,00 (± 9,34) no grupo ECMO-tópico e 24,86 (± 10,374) no IF (P = 0,803). CONCLUSÕES: O presente estudo demonstrou que o ECMO-tópico não é superior a IF para oito horas de preservação pulmonar. .

ABSTRACT

OBJETIVO: Avaliar os efeitos da administração sistêmica precoce e tardia de metilprednisolona nos pulmões em um modelo de morte encefálica em ratos. MÉTODOS: Vinte e quatro ratos Wistar machos foram anestesiados e randomizados em quatro grupos (n = 6 por grupo): sham, somente morte encefálica (ME), metilprednisolona i.v. (30 mg/kg) administrada 5 min após a morte encefálica (MP5) e 60 min após a morte encefálica (MP60). Os grupos ME, MP5 e MP60 foram submetidos à morte encefálica por insuflação de um balão no espaço extradural. Todos os animais foram observados e ventilados durante 120 min. Foram determinadas variáveis hemodinâmicas e gasométricas, relação peso úmido/seco, escore histológico, thiobarbituric acid reactive substances (TBARS, substâncias reativas ao ácido tiobarbitúrico), atividade de superóxido dismutase (SOD) e de catalase, assim como contagem diferencial de células brancas, proteína total e nível de desidrogenase lática no LBA. A atividade da mieloperoxidase, peroxidação lipídica e níveis de TNF-α foram avaliados no tecido pulmonar. RESULTADOS: Não foram observadas diferenças significativas nas variáveis hemodinâmicas e gasométricas, relação peso úmido/seco, análises do LBA, escore histológico, SOD, mieloperoxidase e catalase entre os grupos. Os níveis de TBARS foram significativamente maiores nos grupos MP5 e MP60 do que nos grupos sham e ME (p < 0,001). Os níveis de TNF-α foram significativamente menores nos grupos MP5 e MP60 do que no grupo ME (p < 0,001). CONCLUSÕES: Neste modelo de morte cerebral, a administração precoce e tardia de metilprednisolona apresentou efeitos semelhantes sobre a inflamação e a peroxidação lipídica no tecido pulmonar.


OBJECTIVE: To evaluate the effects that early and late systemic administration of methylprednisolone have on lungs in a rat model of brain death. METHODS: Twenty-four male Wistar rats were anesthetized and randomly divided into four groups (n = 6 per group): sham-operated (sham); brain death only (BD); brain death plus methylprednisolone (30 mg/kg i.v.) after 5 min (MP5); and brain death plus methylprednisolone (30 mg/kg i.v.) after 60 min (MP60). In the BD, MP5, and MP60 group rats, we induced brain death by inflating a balloon catheter in the extradural space. All of the animals were observed and ventilated for 120 min. We determined hemodynamic and arterial blood gas variables; wet/dry weight ratio; histological score; levels of thiobarbituric acid reactive substances (TBARS); superoxide dismutase (SOD) activity; and catalase activity. In BAL fluid, we determined differential white cell counts, total protein, and lactate dehydrogenase levels. Myeloperoxidase activity, lipid peroxidation, and TNF-α levels were assessed in lung tissue. RESULTS: No significant differences were found among the groups in terms of hemodynamics, arterial blood gases, wet/dry weight ratio, BAL fluid analysis, or histological score-nor in terms of SOD, myeloperoxidase, and catalase activity. The levels of TBARS were significantly higher in the MP5 and MP60 groups than in the sham and BD groups (p < 0.001). The levels of TNF-α were significantly lower in the MP5 and MP60 groups than in the BD group (p < 0.001). CONCLUSIONS: In this model of brain death, the early and late administration of methylprednisolone had similar effects on inflammatory activity and lipid peroxidation in lung tissue.

ABSTRACT

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA, punção aspirativa por agulha guiada por ultrassom endobrônquico) tem desempenhado um papel fundamental no diagnóstico de lesões mediastinais, paratraqueais e peribrônquicas, assim como no estadiamento linfonodal da neoplasia pulmonar. Por se tratar de exame endoscópico minimamente invasivo cujo rendimento diagnóstico tem se mostrado comparável aos métodos cirúrgicos estabelecidos, o procedimento de EBUS-TBNA ganhou espaço rapidamente e já se encontra integrado à rotina de investigação em serviços de referência. Para a realização de EBUSTBNA, é importante o planejamento prévio ao procedimento, que deve incluir uma análise minuciosa dos exames radiológicos e cuidado especial com a coleta e preparo do material, além do domínio da técnica e conhecimento de eventuais complicações inerentes ao procedimento. As principais indicações para a realização de EBUS-TBNA são o estadiamento linfonodal da neoplasia pulmonar e a investigação diagnóstica de massas e linfonodomegalias mediastinais ou hilares. Recentemente, iniciou-se a identificação de biomarcadores tumorais em amostras neoplásicas; essa análise molecular no material coletado durante o procedimento de EBUS-TBNA provou ser totalmente possível. Até o momento, o procedimento de EBUS-TBNA não consta nas tabelas de procedimentos médicos da Associação Médica Brasileira. O procedimento de EBUS-TBNA tem se mostrado seguro e eficaz no estadiamento e reestadiamento de neoplasia de pulmão e no esclarecimento diagnóstico de lesões ou linfonodomegalias mediastinais, paratraqueais e peribrônquicas.


Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has played a key role in the diagnosis of mediastinal, paratracheal, and peribronchial lesions, as well as in lymph node staging for lung cancer. Despite its minimally invasive character, EBUS-TBNA has demonstrated a diagnostic yield comparable with that of established surgical methods. It has therefore gained credibility and has become a routine procedure at various referral centers. A successful EBUS-TBNA procedure requires careful planning, which includes a thorough review of the radiological imaging and special care during specimen collection and preparation, as well as technical expertise, experience with the procedure itself, and knowledge of the potential complications inherent to the procedure. The most common indications for EBUS-TBNA include lymph node staging for lung cancer and the diagnostic investigation of mediastinal/hilar masses and lymph node enlargement. Recently, tumor biomarkers in malignant samples collected during the EBUS-TBNA procedure have begun to be identified, and this molecular analysis has proven to be absolutely feasible. The EBUS-TBNA procedure has yet to be included on the Brazilian Medical Association list of medical procedures approved for reimbursement. The EBUS-TBNA procedure has shown to be a safe and accurate tool for lung cancer staging/restaging, as well as for the diagnosis of mediastinal, paratracheal, and peribronchial lesions/lymph node enlargement.

ABSTRACT

CONTEXT

Coagulase-negative staphylococci are common colonizers of the human skin and have become increasingly recognized as agents of clinically significant nosocomial infections. CASE REPORT

The case of a 79-year-old male patient with multi-infarct dementia who presented systemic inflammatory response syndrome is reported. This was attributed to bacteremia due to Staphylococcus cohnii ssp. urealyticus, which was grown on blood cultures originating from an infected pressure ulcer. The few cases of Staphylococcus cohnii infection reported in the literature consist of bacteremia relating to catheters, surgical prostheses, acute cholecystitis, brain abscess, endocarditis, pneumonia, urinary tract infection and septic arthritis, generally presenting a multiresistant profile, with nearly 90% resistance to methicillin. CONCLUSIONS

The reported case is, to our knowledge, the first case of true bacteremia due to Staphylococcus cohnii subsp. urealyticus caused by an infected pressure ulcer. It shows that this species may be underdiagnosed and should be considered in the differential diagnosis for community-acquired skin infections. .


CONTEXTO

Staphylococcus coagulase-negativos, colonizadores frequentes da pele humana, têm sido reconhecidos como agentes de infecções nosocomiais. RELATO DE CASO

Relata-se o caso de um paciente de 79 anos com demência vascular que apresentou síndrome da resposta inflamatória sistêmica atribuída a bacteremia por Staphylococcus cohnni ssp. urealyticus, que cresceu em hemoculturas, secundária a uma úlcera de pressão infectada. Os poucos casos de infecção por Staphylococcus cohnii relatados na literatura descrevem bacteremia associada a cateter, próteses cirúrgicas, colecistite aguda, abscesso cerebral, endocardite, pneumonia, infecção do trato urinário e artrite séptica, geralmente apresentando um perfil de multirresistência, com aproximadamente 90% de resistência à meticilina. CONCLUSÕES

O caso relatado é, ao nosso conhecimento, o primeiro de bacteremia verdadeira por Staphylococcus cohnii subsp. urealyticus causada por uma úlcera por pressão, mostrando que esta espécie pode estar subdiagnosticada e deveria ser considerada no diagnóstico diferencial das infecções cutâneas adquiridas na comunidade. .

ABSTRACT

OBJECTIVE: This study evaluated the performance of lungs that were preserved with different solutions (Celsior, Perfadex or saline) in an ex vivo rat lung perfusion system. METHODS: Sixty Wistar rats were anesthetized, anticoagulated and randomized into three groups (n = 20). The rats were subjected to antegrade perfusion via the pulmonary artery with Perfadex, Celsior, or saline, followed by 6 or 12 hours of ischemia (4ºC, n = 10 in each group). Respiratory mechanics, gas exchange and hemodynamics were measured at 10-minute intervals during the reperfusion of heart-lung blocks in an ex vivo system (IL2-Isolated Perfused Rat or Guinea Pig Lung System, Harvard Apparatus, Holliston, Massachusetts, USA; Hugo Sachs Elektronik, Germany) for 60 minutes. The lungs were prepared for histopathology and evaluated for edema following reperfusion. Group comparisons were performed using ANOVA and the Kruskal-Wallis test with a 5% level of significance. RESULTS: Gas exchange was not significantly different between lungs perfused with either Perfadex or Celsior at the same ischemic times, but it was very low in lungs that were preserved with saline. Airway resistance was greater in the lungs that were preserved for 12 hours. Celsior lungs that were preserved for 6 and 12 hours exhibited lower airway resistance (p = 0.01) compared to Perfadex lungs. Pulmonary artery pressure was not different between the groups, and no significant differences in histopathology and apoptosis were observed between the groups. CONCLUSIONS: Lungs that were preserved with Celsior or Perfadex exhibited similar gas exchange and histopathological findings. Airway resistance was slightly lower in the Celsior-preserved lungs compared with the Perfadex-preserved lungs.

ABSTRACT

FUNDAMENTO: A Disfunção Erétil (DE) se associa ao risco aumentado de Doença Arterial Coronariana (DAC). OBJETIVO: Avaliar a associação entre DE, determinada pelo Índice Internacional de Função Erétil Simplificado (IIFE-5), e DAC. MÉTODOS: Estudo de corte transversal que avaliou 263 hipertensos (55 [50 - 61] anos). A DE foi avaliada pelo IIEF-5 e a DAC, por meio da história de revascularização miocárdica prévia e/ou por cineangiocoronariografia. RESULTADOS: O IIFE-5 se correlacionou com o clearance de creatinina [ClCr] (Rho = 0,23; p < 0,001) e com a idade (Rho = -0,22; p < 0,001). Quarenta e dois pacientes apresentavam DAC; e o IIFE-5 foi capaz de discriminá-los (área sob a curva ROC = 0,63; p = 0,006). Os pacientes foram divididos em dois grupos: IIFE-5 < 20 (n = 140) e IIFE- 5 > 20 (n = 123); aqueles com menor IIFE-5 tinham idade mais elevada (57 [52 - 61] vs. 54 [45 - 60] anos; p = 0,002), maior prevalência de DAC (22% vs. 9%; p = 0,004), tabagismo (64% vs. 47%; p = 0,009) e do uso de inibidores dos canais de cálcio (65 % vs. 43%; p = 0,001), além de menor ClCr (67,3 [30,8 - 88,6] vs. 82,6 [65,9 - 98,2] ml/min; p < 0,001). O IIFE-5 < 20 se associou ao maior risco de DAC em regressão logística; tanto univariada (RR = 2,89 [IC 95% 1,39 - 6,05]), quanto após ajustes para idade, diabetes, ClCr, tabagismo, pressão arterial média e uso de anti- hipertensivos (RR = 2,59 [IC 95%: 1,01 - 6,61]). CONCLUSÃO: O IIFE-5 se associa ao diagnóstico de DAC e sua utilização pode agregar informação ao estadiamento do risco cardiovascular em pacientes hipertensos.


BACKGROUND: Erectile Dysfunction (ED) is associated with increased risk of coronary artery disease (CAD). OBJECTIVE: To evaluate the association between ED, determined by the Simplified International Index of Erectile Function (IIEF-5) and CAD. METHODS: This was a cross-sectional cohort study that evaluated 263 hypertensive patients (55 [50-61] years). ED was assessed through the IIEF-5 and CAD by the history of previous myocardial revascularization and/or coronary angiography. RESULTS: The IIEF-5 correlated with creatinine clearance [CrCl] (Rho = 0.23, p <0.001) and age (Rho = -0.22, p <0.001). Forty-two patients had CAD, and IIEF-5 was able to discriminate them (area under the ROC curve = 0.63, p = 0.006). Patients were divided into two groups: IIEF-5 < 20 (n = 140) and IIEF-5 > 20 (n = 123); those with lower IIEF-5 scores were older (57 [52-61] vs. 54 [45-60] years, p = 0.002), had higher prevalence of CAD (22% vs. 9%, p = 0.004), smoking (64% vs. 47%, p = 0.009) and use of calcium channel inhibitors (65% vs. 43.%, p = 0.001), as well as lower CrCl (67.3 [30.8 to 88.6] vs. 82.6 [65.9 - 98.2] ml/min, p <0.001). The IIEF-5 < 21 was associated with increased risk of CAD in the logistic regression, both univariate (RR = 2.89 [95%CI: 1.39 - 6.05]), and after adjusting for age, diabetes, CrCl, smoking, mean arterial pressure and use of antihypertensive drugs (RR = 2.59 [95% CI: 1.01 - 6.61]). CONCLUSION: The IIEF-5 is associated with the diagnosis of CAD and its use can add information to cardiovascular risk staging in hypertensive patients.
