Comparison between use of a pleural drainage system with flutter valve and a conventional water-seal drainage system after lung resection: a randomized prospective study.

BACKGROUND: There is still a debate regarding the most appropriate pleural collector model to ensure a short hospital stay and minimum complications. OBJECTIVES: To study aimed to compare the time of air leak, time to drain removal, and length of hospital stay between a standard water-seal drainage system and a pleural collector system with a unidirectional flutter valve and rigid chamber. DESIGN AND SETTING: A randomized prospective clinical trial was conducted at a high-complexity hospital in São Paulo, Brazil. METHODS: Sixty-three patients who underwent open or video-assisted thoracoscopic lung wedge resection or lobectomy were randomized into two groups, according to the drainage system used: the control group (WS), which used a conventional water-seal pleural collector, and the study group (V), which used a flutter valve device (Sinapi® Model XL1000®). Variables related to the drainage system, time of air leak, time to drain removal, and time spent in hospital were compared between the groups. RESULTS: Most patients (63%) had lung cancer. No differences were observed between the groups in the time of air leak or time spent hospitalized. The time to drain removal was slightly shorter in the V group; however, the difference was not statistically significant. Seven patients presented with surgery-related complications: five and two in the WS and V groups, respectively. CONCLUSIONS: Air leak, time to drain removal, and time spent in the hospital were similar between the groups. The system used in the V group resulted in no adverse events and was safe.

Lung cancer screening in Brazil: recommendations from the Brazilian Society of Thoracic Surgery, Brazilian Thoracic Association, and Brazilian College of Radiology and Diagnostic Imaging.

Although lung cancer (LC) is one of the most common and lethal tumors, only 15% of patients are diagnosed at an early stage. Smoking is still responsible for more than 85% of cases. Lung cancer screening (LCS) with low-dose CT (LDCT) reduces LC-related mortality by 20%, and that reduction reaches 38% when LCS by LDCT is combined with smoking cessation. In the last decade, a number of countries have adopted population-based LCS as a public health recommendation. Albeit still incipient, discussion on this topic in Brazil is becoming increasingly broad and necessary. With the aim of increasing knowledge and stimulating debate on LCS, the Brazilian Society of Thoracic Surgery, the Brazilian Thoracic Association, and the Brazilian College of Radiology and Diagnostic Imaging convened a panel of experts to prepare recommendations for LCS in Brazil. The recommendations presented here were based on a narrative review of the literature, with an emphasis on large population-based studies, systematic reviews, and the recommendations of international guidelines, and were developed after extensive discussion by the panel of experts. The following topics were reviewed: reasons for screening; general considerations about smoking; epidemiology of LC; eligibility criteria; incidental findings; granulomatous lesions; probabilistic models; minimum requirements for LDCT; volumetric acquisition; risks of screening; minimum structure and role of the multidisciplinary team; practice according to the Lung CT Screening Reporting and Data System; costs versus benefits of screening; and future perspectives for LCS.

RESUMO O câncer de pulmão (CP) é uma das neoplasias mais comuns e letais no Brasil, e apenas 15% dos pacientes são diagnosticados nos estágios iniciais. O tabagismo persiste como o responsável por mais de 85% de todos os casos. O rastreamento do CP (RCP) por meio da TC de baixa dosagem de radiação (TCBD) reduz a mortalidade do CP em 20%, e, quando combinado com a cessação do tabagismo, essa redução chega a 38%. Na última década, diversos países adotaram o RCP como recomendação de saúde populacional. No Brasil, embora ainda incipiente, a discussão sobre o tema é cada vez mais ampla e necessária. Com o intuito de aumentar o conhecimento e estimular o debate sobre o RCP, a Sociedade Brasileira de Cirurgia Torácica, a Sociedade Brasileira de Pneumologia e Tisiologia e o Colégio Brasileiro de Radiologia e Diagnóstico por Imagem constituíram um painel de especialistas para elaborar as recomendações para o RCP. As recomendações aqui apresentadas foram baseadas em revisão narrativa da literatura, com ênfase em grandes estudos populacionais, em revisões sistemáticas e em recomendações de diretrizes internacionais, sendo construídas após ampla discussão pelo grupo de especialistas. Os temas revisados foram os seguintes: porque rastrear, considerações gerais sobre tabagismo, epidemiologia do CP, critérios de elegibilidade, achados incidentais, lesões granulomatosas, modelos probabilísticos, requisitos mínimos da TCBD, aquisições volumétricas, riscos do rastreamento, estrutura mínima e papel da equipe multidisciplinar, conduta segundo o Lung CT Screening Reporting and Data System (Lung-RADS), custos vs. benefícios e perspectivas do rastreamento.

Challenges of Implementing Lung Cancer Screening in a Developing Country: Results of the Second Brazilian Early Lung Cancer Screening Trial (BRELT2).

PURPOSE: This paper aims to present the results of a series of several Brazilian institutions that have been carrying out lung cancer screening (LCS). MATERIALS AND METHODS: This is a retrospective, cohort study, with follow-up of individuals of both sexes, with a heavy smoking history, who participated in LCS programs between December 2013 and January 2021 in six Brazilian institutions located in the states of São Paulo, Rio Grande do Sul, and Bahia. RESULTS: Three thousand four hundred seventy individuals were included, of which 59.8% were male (n = 2,074) and 50.6% were current smokers (n = 1,758), with 60.7 years (standard deviation 8.8 years). Lung-RADS 4 was observed in 233 (6.7%) patients. Biopsy was indicated by minimally invasive methods in 122 patients (3.5%). Two patients who demonstrated false-negative biopsies and lung cancer were diagnosed in follow-up. Diagnosis of lung cancer was observed in 74 patients (prevalence rate of 2.1%), with 52 (70.3%) in stage I or II. Granulomatous disease was found in 20 patients. There were no statistical differences in the incidence of lung cancer, biopsies, granulomatous disease, and Lung-RADS 4 nodules between public and private patients. CONCLUSION: There are still many challenges and obstacles in the implementation of LCS in developing countries; however, our multi-institutional data were possible to obtain satisfactory results in these scenarios and to achieve similar results to the main international studies. Granulomatous diseases did not increase the number of lung biopsies. The authors hope that it could stimulate the creation of organized screening programs in regions still endemic for tuberculosis and other granulomatous diseases.

Role that anorexia and weight loss play in patients with stage IV lung cancer.

OBJECTIVE: To evaluate the prevalence of anorexia and weight loss at diagnosis (pre-treatment), to identify the factors associated with pre-treatment weight loss, and to determine the prognostic role of anorexia and weight loss in the overall survival of patients with stage IV lung cancer. METHODS: This was a retrospective observational cohort study. The patients were stratified by the presence/absence of anorexia and of pre-treatment weight loss, which generated a measure composed of four categories, which were the independent variables. RESULTS: Among the 552 patients included in the study, anorexia and pre-treatment weight loss were present in 39.1% and 70.1%, respectively. After adjusting for age, male gender, and Karnofsky performance status, we found that anorexia and tumor size were significantly associated with pre-treatment weight loss. In a Cox multivariate analysis, adjusted for age, male gender and low Karnofsky performance status were found to be independent predictors of worse survival, as was concomitance of anorexia and weight loss. CONCLUSIONS: Anorexia and pre-treatment weight loss appear to be relevant problems in the follow-up of patients with advanced (stage IV) lung cancer Specific interventions are of crucial importance in individualized treatment plans, even within the context of palliative care.

Role that anorexia and weight loss play in patients with stage IV lung cancer / Papel do binômio anorexia e perda de peso em pacientes com câncer de pulmão em estádio IV

RESUMO Objetivo: Avaliar a prevalência de anorexia e perda de peso ao diagnóstico (pré-tratamento), os fatores associados à perda de peso pré-tratamento e o papel prognóstico da anorexia e da perda de peso na sobrevida global de pacientes com câncer de pulmão em estádio IV. Métodos: Estudo de coorte retrospectivo observacional. Os pacientes foram estratificados, dependendo da presença/ausência de anorexia e da presença/ausência de perda de peso pré-tratamento, o que gerou uma medida composta de anorexia e perda de peso de quatro níveis, que foi a variável independente. Resultados: Entre os 552 pacientes incluídos no estudo, as prevalências de anorexia e de perda de peso pré-tratamento foram de 39,1% e 70,1%, respectivamente. Após ajustar para idade, sexo masculino e índice de Karnofsky, a presença de anorexia e o tamanho do tumor foram significativamente associados à perda de peso pré-tratamento. Na análise multivariada de Cox, após ajustar para a idade, as variáveis sexo masculino, presença concomitante de anorexia e perda de peso e índice de Karnofsky reduzido foram preditores independentes de pior probabilidade de sobrevida. Conclusões: O presente estudo demonstrou que a presença de anorexia e de perda de peso pré-tratamento são problemas relevantes no seguimento de pacientes com câncer de pulmão avançado (estádio IV). Intervenções específicas são de crucial importância no plano de assistência individualizada, mesmo dentro da proposta de cuidados paliativos.

CT-guided percutaneous core needle biopsy of pulmonary nodules smaller than 2 cm: technical aspects and factors influencing accuracy.

OBJECTIVE: To evaluate the diagnostic accuracy of CT-guided percutaneous core needle biopsy (CT-CNB) of pulmonary nodules ≤ 2 cm, as well as to identify factors influencing the accuracy of the procedure and its morbidity. METHODS: This was a retrospective, single-center study of 170 consecutive patients undergoing CT-CNB of small pulmonary nodules (of ≤ 2 cm) between January of 2010 and August of 2015. RESULTS: A total of 156 CT-CNBs yielded a definitive diagnosis, the overall diagnostic accuracy being 92.3%. Larger lesions were associated with a higher overall accuracy (OR = 1.30; p = 0.007). Parenchymal hemorrhage occurring during the procedure led to lower accuracy rates (OR = 0.13; p = 0.022). Pneumothorax was the most common complication. A pleura-to-lesion distance > 3 cm was identified as a risk factor for pneumothorax (OR = 16.94), whereas performing a blood patch after biopsy was a protective factor for pneumothorax (OR = 0.18). CONCLUSIONS: Small nodules (of < 2 cm) represent a technical challenge for diagnosis. CT-CNB is an excellent diagnostic tool, its accuracy being high.

Challenges in Lung Cancer Screening in Latin America.

Lung cancer is the deadliest cancer worldwide and is of particular concern for Latin America. Its rising incidence in this area of the world poses myriad challenges for the region's economies, which are already struggling with limited resources to meet the health care needs of low- and middle-income populations. In this environment, we are concerned that regional governments are relatively unaware of the pressing need to implement effective strategies for the near future. Low-dose chest computed tomography (LDCT) for screening, and routine use of minimally invasive techniques for diagnosis and staging remain uncommon. According to results of the National Lung Screening Trial, LDCT lung cancer screening provided a 20% relative reduction in mortality rates among at-risk individuals. Nevertheless, this issue is still a matter of debate, particularly in developing countries, and it is not fully embraced in developing countries. The aim of this article is to provide an overview of what the standard of care is for lung cancer computed tomography screening around the world and to aid understanding of the challenges and potential solutions that can help with the implementation of LDCT in Latin America.

RESUMO Objetivo: Avaliar a precisão diagnóstica da biópsia percutânea com agulha grossa, guiada por TC - doravante denominada BAG-TC - de nódulos pulmonares ≤ 2 cm, bem como identificar fatores que influenciam a precisão do procedimento e sua morbidade. Métodos: Estudo retrospectivo, realizado em um único centro, com 170 pacientes consecutivos submetidos a BAG-TC de nódulos pulmonares pequenos (≤ 2 cm) entre janeiro de 2010 e agosto de 2015. Resultados: Do total de biópsias, 156 resultaram em diagnóstico definitivo, com precisão diagnóstica global de 92,3%. Lesões maiores estiveram relacionadas com maior precisão global (OR = 1,30; p = 0,007). A presença de hemorragia parenquimatosa durante o procedimento resultou em menor precisão (OR = 0,13; p = 0,022). Pneumotórax foi a complicação mais comum. Uma distância > 3 cm entre a lesão e a pleura foi identificada como fator de risco de pneumotórax (OR = 16,94), ao passo que a realização de tampão sanguíneo após a biópsia foi um fator de proteção contra o pneumotórax (OR = 0,18). Conclusões: O diagnóstico de nódulos pequenos (< 2 cm) é um desafio do ponto de vista técnico. A BAG-TC é uma excelente ferramenta diagnóstica, cuja precisão é alta.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in diagnosis of mediastinal lesions.

OBJECTIVE: To describe the results of endobronchial ultrasound-guided transbronchial needle aspiration in making diagnosis of mediastinal injuries associated to different causes. METHODS: A retrospective cross-sectional study of patients submitted to Endobronchial ultrasound-guided transbronchial needle aspiration at a private organization, between June 2013 and October 2016. All cases referred for collection of lymph nodes or peritracheal/peribronchial masses by endobronchial ultrasound-guided transbronchial needle aspiration, and evaluated through tomography or PET-CT were included. Interventional pulmonologists and thoracic surgeons with experience in the method did the procedures. Rapid on-site evaluation of fine needle aspiration was performed by an experienced pathologist. Material analysis included cytological smear and cytopathological analysis of paraffin-embedded cell blocks. Other specific analyses (immunocytochemistry, tests and cultures of infectious agents) were performed whenever necessary. RESULTS: We included 72 patients; 6 were excluded for presenting endobronchial lesions in which bronchoscopic biopsy could be performed, or intrathoracic lesions that were not accessible by endobronchial ultrasound-guided transbronchial needle aspiration. The mean age of 66 patients included for analysis was 61.17 years (±14.67 years), with a predominance of males (64%). Endobronchial ultrasound-guided transbronchial needle aspiration was definitive for diagnosis in 60 cases (91%). Three cases (4.5%) had inconclusive test results. There were no major complications related to the procedure. CONCLUSION: Endobronchial ultrasound-guided transbronchial needle aspiration had a high diagnosis yield, with minimal morbidity, being an excellent option for diagnostic approach of patients with lymphadenopathy or intrathoracic lesions, and for neoplasm staging.

Survival in a cohort of patients with lung cancer: the role of age and gender in prognosis / Sobrevida em uma coorte de pacientes com câncer de pulmão: papel da idade e do sexo no prognóstico

ABSTRACT Objective: To determine the demographic and clinical characteristics of patients with non-small cell lung cancer (NSCLC), as well as their disease course, by age group and gender. Methods: This was a retrospective cohort study of patients diagnosed with NSCLC from 2000 to 2012 and followed until July 2015 in a tertiary referral hospital in the city of São Paulo, Brazil. Based on the 25th and 75th percentiles of the age distribution, patients were stratified into three age groups: < 55 years; ≥ 55 and < 72 years; and ≥ 72 years. Survival time was evaluated during the follow-up period of the study. Functions of overall and gender-specific survival stratified by age groups (event: all-cause mortality) were calculated using the Kaplan-Meier method. Differences among survival curves were assessed via the log-rank test. Results: We included 790 patients with the following age distribution: < 55 years, 165 patients; ≥ 55 and < 72 years, 423; and ≥ 72 years, 202. In the entire sample, there were 493 men (62.4%). Adenocarcinoma was the most common histological pattern in the < 72-year age groups; 575 patients (73%) presented with advanced disease (stages IIIB-IV). The median 5-year survival was 12 months (95% CI: 4-46 months), with no significant differences among the age groups studied. Conclusions: NSCLC remains more common in men, although we found an increase in the proportion of the disease in women in the < 55-year age group. Adenocarcinoma predominated in women. In men, squamous cell carcinoma predominated in the ≥ 72-year age group. Most patients presented with advanced-stage disease at diagnosis. There were no statistical differences in survival between genders or among age groups.

RESUMO Objetivo: Analisar características demográficas e clínicas, assim como a evolução de pacientes com câncer de pulmão de células não pequenas (CPCNP) de acordo com a faixa etária e o sexo desses pacientes. Métodos: Coorte retrospectiva de pacientes diagnosticados com CPCNP entre janeiro de 2000 e julho de 2012, acompanhados até julho de 2015, em um hospital terciário de referência no município de São Paulo. Com base na distribuição de idade segundo os percentis 25 e 75, os pacientes foram estratificados em três grupos: < 55 anos; ≥ 55 e < 72 anos; e ≥ 72 anos. O tempo de sobrevida foi avaliado durante o período de acompanhamento do estudo. As funções de sobrevida geral e por sexo estratificada por faixa etária (considerando-se óbito por qualquer motivo) foram calculadas empregando-se o método de Kaplan-Meier. As diferenças entre as curvas de sobrevida foram verificadas pelo teste log-rank. Resultados: Foram incluídos 790 pacientes, com a seguinte distribuição etária: 165, 423 e 202 pacientes, respectivamente, com < 55 anos; ≥ 55 e < 72 anos; e ≥ 72 anos. Na amostra geral, havia 493 homens (62,4%). O padrão histológico mais frequente foi adenocarcinoma nos grupos com < 72 anos; 575 pacientes (73%) apresentavam doença avançada (estádios IIIB-IV). A mediana de sobrevida em 5 anos foi de 12 meses (IC95%: 4-46), sem diferenças significantes nas faixas etárias estudadas. Conclusões: O CPCNP continua sendo mais frequente em homens, apesar de ter havido um aumento de sua proporção em mulheres na faixa etária < 55 anos. O adenocarcinoma predominou nas mulheres. Nos homens, o carcinoma escamoso predominou no grupo ≥ 72 anos. A maioria dos casos apresentava-se em estádio avançado ao diagnóstico. Não foram observadas diferenças estatísticas na sobrevida entre os sexos ou as faixas etárias.

Family caregiver burden: the burden of caring for lung cancer patients according to the cancer stage and patient quality of life / Sobrecarga do cuidador familiar: a sobrecarga de cuidar de pacientes com câncer de pulmão, de acordo com o estágio do câncer e a qualidade de vida do paciente

ABSTRACT Objective: Patients with lung cancer experience different feelings and reactions, based on their family, social, cultural, and religious backgrounds, which are a source of great distress, not only for the patients but also for their family caregivers. This study aimed to evaluate the impact that lung cancer stage and quality of life (QoL) of lung cancer patients have on caregiver burden. Methods: This was a prospective cross-sectional study. Consecutive patient-caregiver dyads were selected and asked to complete the Hospital Anxiety and Depression Scale and the Medical Outcomes Study 36-item ShortForm Health Survey (SF-36). Family caregivers also completed the Caregiver Burden Scale. Group-based modeling was used in order to identify patients with early- or advanced-stage cancer (IA to IIIA vs. IIIB to IV) plus non-impaired or impaired QoL (SF36 total score > 50 vs. ≤ 50). Patient-caregiver dyads were stratified into four groups: early-stage cancer+non-impaired QoL; advanced-stage cancer+non-impaired QoL; early-stage cancer+impaired QoL; and advanced-stage cancer+impaired QoL. Results: We included 91 patient-caregiver dyads. The majority of the patients were male and heavy smokers. Family caregivers were younger and predominantly female. The burden, QoL, level of anxiety, and level of depression of caregivers were more affected by the QoL of the patients than by their lung cancer stage. The family caregivers of the patients with impaired QoL showed a higher median burden than did those of the patients with non-impaired QoL, regardless of disease stage. Conclusions: Caregiver burden is more affected by patient QoL than by lung cancer stage.

RESUMO Objetivo: Pacientes com câncer de pulmão vivenciam diferentes sentimentos e reações, dependendo de sua formação familiar, social, cultural e religiosa, que são fonte de grande sofrimento, não só para os pacientes mas também para seus cuidadores familiares. Este estudo objetivou avaliar o impacto do estágio do câncer de pulmão e da qualidade de vida (QV) dos pacientes com câncer de pulmão na sobrecarga do cuidador. Métodos: Estudo prospectivo transversal. Díades paciente-cuidador foram selecionadas consecutivamente e solicitadas a preencher a Hospital Anxiety and Depression Scale e o Medical Outcomes Study 36-item Short-Form Health Survey (SF-36). Os cuidadores familiares também preencheram a Caregiver Burden Scale. Utilizou-se a modelagem de grupos para identificar pacientes com câncer em estágio inicial ou avançado (IA a IIIA vs. IIIB a IV) mais QV não comprometida ou comprometida (pontuação total no SF36 > 50 vs. ≤ 50). As díades paciente-cuidador foram estratificadas em quatro grupos: câncer em estágio inicial+QV não comprometida; câncer em estágio avançado+QV não comprometida; câncer em estágio inicial+QV comprometida; e câncer em estágio avançado+QV comprometida. Resultados: Foram incluídas 91 díades paciente-cuidador. A maioria dos pacientes era do sexo masculino e grande fumante. Os cuidadores familiares eram mais jovens e predominantemente do sexo feminino. A sobrecarga, QV, nível de ansiedade e nível de depressão dos cuidadores foram mais afetados pela QV dos pacientes do que pelo estágio do câncer de pulmão. Os cuidadores familiares dos pacientes com QV comprometida apresentaram maior mediana de sobrecarga do que os dos pacientes com QV não comprometida, independentemente do estágio da doença. Conclusões: A sobrecarga do cuidador é mais afetada pela QV do paciente do que pelo estágio do câncer de pulmão.

As díades paciente-cuidador foram estratificadas em quatro grupos: câncer em estágio inicial+QV não comprometida; câncer em estágio avançado+QV não comprometida; câncer em estágio inicial+QV comprometida; e câncer em estágio avançado+QV comprometida. RESULTADOS:: Foram incluídas 91 díades paciente-cuidador. A maioria dos pacientes era do sexo masculino e grande fumante. Os cuidadores familiares eram mais jovens e predominantemente do sexo feminino. A sobrecarga, QV, nível de ansiedade e nível de depressão dos cuidadores foram mais afetados pela QV dos pacientes do que pelo estágio do câncer de pulmão. Os cuidadores familiares dos pacientes com QV comprometida apresentaram maior mediana de sobrecarga do que os dos pacientes com QV não comprometida, independentemente do estágio da doença. CONCLUSÕES:: A sobrecarga do cuidador é mais afetada pela QV do paciente do que pelo estágio do câncer de pulmão.

Survival in a cohort of patients with lung cancer: the role of age and gender in prognosis.

OBJECTIVE: To determine the demographic and clinical characteristics of patients with non-small cell lung cancer (NSCLC), as well as their disease course, by age group and gender. METHODS: This was a retrospective cohort study of patients diagnosed with NSCLC from 2000 to 2012 and followed until July 2015 in a tertiary referral hospital in the city of São Paulo, Brazil. Based on the 25th and 75th percentiles of the age distribution, patients were stratified into three age groups: < 55 years; ≥ 55 and < 72 years; and ≥ 72 years. Survival time was evaluated during the follow-up period of the study. Functions of overall and gender-specific survival stratified by age groups (event: all-cause mortality) were calculated using the Kaplan-Meier method. Differences among survival curves were assessed via the log-rank test. RESULTS: We included 790 patients with the following age distribution: < 55 years, 165 patients; ≥ 55 and < 72 years, 423; and ≥ 72 years, 202. In the entire sample, there were 493 men (62.4%). Adenocarcinoma was the most common histological pattern in the < 72-year age groups; 575 patients (73%) presented with advanced disease (stages IIIB-IV). The median 5-year survival was 12 months (95% CI: 4-46 months), with no significant differences among the age groups studied. CONCLUSIONS: NSCLC remains more common in men, although we found an increase in the proportion of the disease in women in the < 55-year age group. Adenocarcinoma predominated in women. In men, squamous cell carcinoma predominated in the ≥ 72-year age group. Most patients presented with advanced-stage disease at diagnosis. There were no statistical differences in survival between genders or among age groups.

Burnout syndrome: prevalence in healthprofessionals working in the area of oncology / Síndrome de burnout: prevalência em profissionais da saúde que atuam na área de oncologia

Healthcare professionals who work in the area of caregiving are responsible for the ongoing care of patients and therefore are more vulnerable to burnout. The objective of this study is to evaluate the levels of stress in health professionals, and to analyze the quality of life, and the level of anxiety and depression among these individuals. A cross-sectional study was carried out with professionals working in the oncology unit, both men and women, over 18 years of age, who agreed to participate in the study and signed an informed consent form. Participants completed the evaluation form and completed the SF-36 Quality of Life, Hospital Anxiety and Depression Scale (HADS), and Maslach Burnout Inventory (MBI) questionnaire. We evaluated 54 professionals, predominantly female and young. When comparing quality of life and level of anxiety or depression among the different subgroups of employees, it was possible to observe that, in the dimensions of emotional exhaustion and low professional achievement, individuals with higher stress had worse quality of life and higher level of anxiety and depression. For the dimension of depersonalization, only anxiety was higher in subjects with moderate stress. This study demonstrated that many professionals have moderate or high degree of professional stress and that this was associated with greater anxiety and depression and poorer quality of life. These results may provide useful insights to improve the physical and mental health of health care professionals

Os profissionais da saúde que atuam na área de assistência são responsáveis pelo cuidado contínuo dos pacientes e, por isso, estão mais vulneráveis ao burnout. O objetivo deste estudo foi avaliar os níveis de estresse em profissionais da saúde e analisar a qualidade de vida e o nível de ansiedade e depressão entre esses indivíduos. Foi realizado estudo transversal, com profissionais que atuam na área assistencial de unidade de oncologia, de ambos os sexos, maiores de 18 anos e que aceitaram participar da pesquisa e assinaram o termo de consentimento livre e esclarecido. Os participantes preencheram ficha de avaliação e responderam ao questionário de qualidade de vida SF-36, à Escala Hospitalar de Ansiedade e Depressão (HADS) e ao Inventário de Burnout de Maslach (MBI). Foram avaliados 54 profissionais, predominando sexo feminino e faixa etária jovem. Ao comparar qualidade de vida e nível de ansiedade ou depressão entre os diferentes subgrupos de funcionários, foi possível observar que nas dimensões de exaustão emocional e baixa realização profissional os indivíduos com maior grau de estresse apresentaram pior qualidade de vida e maior nível de ansiedade e depressão. Para a dimensão de despersonalização, apenas a ansiedade se mostrou maior nos indivíduos com grau moderado de estresse. Este estudo demonstrou que muitos profissionais possuem grau moderado ou alto de estresse profissional e que isso se associou com maior ansiedade e depressão e pior qualidade de vida. Esses resultados podem fornecer conhecimentos úteis para melhorar a saúde física e mental dos profissionais da área da saúde

Computed Tomography-Guided Percutaneous Thoracic Duct Sclero-Embolization for Persistent Chylothorax.

Postoperative chylous leak is often a consequence of thoracic duct injury during surgical procedures. Persistent chylothorax can be an extremely morbid condition. The authors describe a case of a refractory and long-standing chylous leak after thoracotomy for mediastinal lymphangioma removal. The patient was treated with a computed tomography-guided percutaneous thoracic duct sclero-embolization after failure of the conventional therapies. The chest tube output abruptly decreased after the procedure and was removed at 13th day. Percutaneous thoracic duct sclero-embolization proved to be safe and effective in the treatment of a persistent chylothorax.

Retrospective study of the physical therapy modalities applied in head and neck l ymphedema treatment.

BACKGROUND: Secondary lymphedema after head and neck cancer treatment is a serious complication and its management can be a challenge. The purpose of this study was to verify which physical therapy modalities were applied in the treatment of head and neck lymphedema through a retrospective analysis. METHODS: A retrospective study was developed, based on the analysis of medical records of 32 patients treated in the physiotherapy outpatient department of the Brazilian Institute of Cancer Control (IBCC). RESULTS: The physiotherapy included manual lymphatic drainage, massage, exercises, patient education, and compression therapy with an average of 23.9 ± 14.8 sessions. Measurement results showed a significant reduction of face and neck lymphedema (p < .05) and pain (from 7.8 ± 2.2 to 3.6 ± 1.6; p < .001). CONCLUSION: The physical therapy modalities based on strategic manual lymphatic drainage, shoulder girdle massage, facial, tongue and neck exercises, compressive therapy at home, and patient education showed reduction of the lymphedema and pain, both of them secondary to head and neck cancer treatment.
