Antifibrotic therapy in idiopathic pulmonary fibrosis candidates for lung transplantation undergoing pulmonary rehabilitation.

OBJECTIVE: To investigate the impact of pulmonary rehabilitation (PR) on functional outcomes and health-related quality of life (HRQoL) in idiopathic pulmonary fibrosis (IPF) patients placed on a lung transplant waitlist and receiving antifibrotic therapy (AFT). METHODS: This was a retrospective observational study of consecutive IPF patients receiving AFT with either pirfenidone or nintedanib (the AFT group) and undergoing PR between January of 2018 and March of 2020. The AFT group and the control group (i.e., IPF patients not receiving AFT) participated in a 12-week PR program consisting of 36 sessions. After having completed the program, the study participants were evaluated for the six-minute walk distance (6MWD) and HRQoL. Pre- and post-PR 6MWD and HRQoL were compared within groups and between groups. RESULTS: There was no significant difference between the AFT and control groups regarding baseline characteristics, including age, airflow limitation, comorbidities, and oxygen requirement. The AFT group had a significant increase in the 6MWD after 12 weeks of PR (effect size, 0.77; p < 0.05), this increase being significant in the between-group comparison as well (effect size, 0.55; p < 0.05). The AFT group showed a significant improvement in the physical component of HRQoL at 12 weeks (effect size, 0.30; p < 0.05). CONCLUSIONS: Among IPF patients undergoing PR, those receiving AFT appear to have greater improvements in the 6MWD and the physical component of HRQoL than do those not receiving AFT.

Ambulatory oxygen therapy in lung transplantation candidates with idiopathic pulmonary fibrosis referred for pulmonary rehabilitation.

OBJECTIVE: To determine independent factors related to the use of oxygen and the oxygen flow rate in idiopathic pulmonary fibrosis (IPF) patients placed on a lung transplant waitlist and undergoing pulmonary rehabilitation (PR). METHODS: This was a retrospective quasi-experimental study presenting functional capacity and health-related quality of life (HRQoL) data from lung transplant candidates with IPF referred for PR and receiving ambulatory oxygen therapy. The patients were divided into three groups on the basis of the oxygen flow rate: 0 L/min (the control group), 1-3 L/min, and 4-5 L/min. Data on functional capacity were collected by means of the six-minute walk test, and data on HRQoL were collected by means of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36), being collected before and after 36 sessions of PR including aerobic and strength exercises. RESULTS: The six-minute walk distance improved in all three groups (0 L/min: Δ 61 m, p < 0.001; 1-3 L/min: Δ 58 m, p = 0.014; and 4-5 L/min: Δ 35 m, p = 0.031). Regarding HRQoL, SF-36 physical functioning domain scores improved in all three groups, and the groups of patients receiving ambulatory oxygen therapy had improvements in other SF-36 domains, including role-physical (1-3 L/min: p = 0.016; 4-5 L/min: p = 0.040), general health (4-5 L/min: p = 0.013), social functioning (1-3 L/min: p = 0.044), and mental health (1-3 L/min: p = 0.046). CONCLUSIONS: The use of ambulatory oxygen therapy during PR in lung transplant candidates with IPF and significant hypoxemia on exertion appears to improve functional capacity and HRQoL.

CT imaging findings in lung transplant recipients with COVID-19.

OBJECTIVES: Our goal was to compare the chest computed tomography (CT) imaging findings of COVID-19 in lung transplant recipients (LTR) and a group of non-transplanted controls (NTC). METHODS: This retrospective study included 51 consecutive LTR hospitalized with COVID-19 from two centers. A total of 75 NTC were included for comparison. Images were classified regarding the standardized RSNA category, main pattern of lung attenuation, and longitudinal and axial distribution. Quantitative CT (QCT) analysis was performed to evaluate percentage of high attenuation areas (%HAA, threshold -250 to -700 HU). CT scoring was used to measure severity of parenchymal abnormalities. RESULTS: The imaging findings of COVID-19 in LTR were significantly different from controls regarding the RSNA classification and pattern of lung attenuation. LTR had a significantly higher proportion of patients with an indeterminate pattern on CT (0.31 vs. 0.11, p = 0.014). The most frequent pattern of attenuation in LTR was predominantly consolidation (0.39 vs. 0.22, p = 0.144) followed by a mixed pattern of ground-glass opacities (GGO) and consolidation (0.37 vs. 0.20, adjusted p = 0.102). On the other hand, the most common pattern in NTC was GGO predominant (0.58 vs. 0.24 of LTR, p = 0.001). LTR had significantly more severe parenchymal disease measured by CT score and %HAA by QCT (0.372 ± 0.08 vs. 0.148 ± 0.06, p < 0.001). CONCLUSION: The most frequent finding of COVID-19 in LTR is a predominant pattern of consolidation. Compared to NTC, LTR more frequently demonstrated an indeterminate pattern according to the RSNA classification and more extensive lung abnormalities on QCT and semi-quantitative scoring. KEY POINTS: • The most common CT finding of COVID-19 in LTR is a predominant pattern of consolidation followed by a mixed pattern of GGO and consolidation, while controls more often have a predominant pattern of GGO. • LTR more often presents with an indeterminate pattern of COVID-19 by RSNA classification than controls; therefore, molecular testing for COVID-19 is essential for LTR presenting with lower airway infection independently of imaging findings. • LTR had more extensive disease by semi-quantitative CT score and increased percentage areas of high attenuation on QCT.

RESUMO Objetivo: Investigar o impacto da reabilitação pulmonar (RP) em desfechos funcionais e na qualidade de vida relacionada à saúde (QVRS) em pacientes com fibrose pulmonar idiopática (FPI) em lista de espera para transplante de pulmão e em tratamento com antifibróticos (AF). Métodos: Estudo observacional retrospectivo com pacientes consecutivos com FPI em tratamento com pirfenidona ou nintedanibe (grupo AF) submetidos a RP entre janeiro de 2018 e março de 2020. O grupo AF e o grupo controle (pacientes com FPI que não estavam em tratamento com AF) participaram de um programa de RP com 36 sessões ao longo de 12 semanas. Após o término do programa, os participantes foram avaliados quanto à distância percorrida no teste de caminhada de seis minutos (DTC6) e à QVRS. A DTC6 e a QVRS pré e pós-RP foram comparadas intra e intergrupos. Resultados: Não houve diferença significativa entre os grupos AF e controle quanto às características basais, incluindo idade, limitação do fluxo aéreo, comorbidades e necessidade de oxigênio. O grupo AF apresentou um aumento significativo da DTC6 após 12 semanas de RP (tamanho do efeito: 0,77; p < 0,05); esse aumento também foi significativo na comparação intergrupos (tamanho do efeito: 0,55; p < 0,05). O grupo AF apresentou melhora significativa no componente físico da QVRS após 12 semanas (tamanho do efeito: 0,30; p < 0,05). Conclusões: Em pacientes com FPI submetidos a RP, a melhora na DTC6 e no componente físico da QVRS parece ser maior naqueles que estejam recebendo tratamento com AF do que naqueles que não o estejam.

No tocante à QVRS, a pontuação obtida no domínio "capacidade funcional" do SF-36 melhorou nos três grupos, e os pacientes que receberam oxigenoterapia ambulatorial apresentaram melhora em outros domínios do SF-36: função física (1-3 L/min: p = 0,016; 4-5 L/min: p = 0,040), estado geral de saúde (4-5 L/min: p = 0,013), aspectos sociais (1-3 L/min: p = 0,044) e saúde mental (1-3 L /min: p = 0,046). Conclusões: O uso de oxigenoterapia ambulatorial durante a RP em candidatos a transplante de pulmão com FPI e hipoxemia significativa aos esforços parece melhorar a capacidade funcional e a QVRS.

Utilization of Quantitative Computed Tomography Assessment to Identify Bronchiolitis Obliterans Syndrome After Single Lung Transplantation.

OBJECTIVE: To evaluate quantitative chest computed tomography (CT) methods for the detection of air trapping (AT) and to assess its diagnostic performance for the diagnosis of bronchiolitis obliterans syndrome (BOS) in single lung transplant (SLT) patients. METHODS: Adult patients who had a SLT at a single transplant center and underwent CT scan after transplantation were retrospectively included. CT findings of air trapping were measured by three different methods: expiratory air-trapping index (ATIexp), mean lung density on expiratory acquisition (MLDexp) and expiratory to inspiratory ratio of mean lung density (E/I-ratio(MLD). Sensitivity, specificity and diagnostic accuracy of the three methods for the detection of BOS status evaluated by serial routine measures of pulmonary function tests (gold standard) were assessed. RESULTS: Forty-six SLT patients (52.2% females, mean age 58 ± 6 years) were included in the analysis, 12 (26%) patients with a diagnosis of BOS. Quantitative CT diagnosis of AT ranged from 26 to 35%. Sensitivity, specificity and accuracy of each method for the detection of BOS were 85.7%, 84.7% and 85.0% for ATIexp, 78.5%, 93.4% and 90.0% for MLD and 64.2%, 89.1% and 83.3% E/I-ratio(MLD), respectively. CONCLUSION: Quantitative measures of AT obtained from standard CT are feasible and show high specificity and accuracy for the detection of BOS in SLT patients.

Computer-aided Diagnosis of Skin Cancer: A Review.

Cancer is currently one of the main health issues in the world. Among different varieties of cancers, skin cancer is the most common cancer in the world and accounts for 75% of the world's cancer. Indeed, skin cancer involves abnormal changes in the outer layer of the skin. Although most people with skin cancer recover, it is one of the major concerns of people due to its high prevalence. Most types of skin cancers grow only locally and invade adjacent tissues, but some of them, especially melanoma (cancer of the pigment cells), which is the rarest type of skin cancer, may spread through the circulatory system or lymphatic system and reach the farthest points of the body. Many papers have been reviewed about the application of image processing in cancer detection. In this paper, the automatic skin cancer detection and also different steps of such a process have been discussed based on the implantation capabilities.

Pulmonary rehabilitation improves survival in patients with idiopathic pulmonary fibrosis undergoing lung transplantation.

This study was conducted to evaluate whether a pulmonary rehabilitation program (PRP) is independently associated with survival in patients with idiopathic pulmonary fibrosis (IPF) undergoing lung transplant (LTx). This quasi-experimental study included 89 patients who underwent LTx due to IPF. Thirty-two completed all 36 sessions in a PRP while on the waiting list for LTx (PRP group), and 53 completed fewer than 36 sessions (controls). Survival after LTx was the main outcome; invasive mechanical ventilation (IMV), length of stay (LOS) in intensive care unit (ICU) and in hospital were secondary outcomes. Kaplan-Meier curves and Cox regression models were used in survival analyses. Cox regression models showed that the PRP group had a reduced 54.0% (hazard ratio = 0.464, 95% confidence interval 0.222-0.970, p = 0.041) risk of death. A lower number of patients in the PRP group required IMV for more than 24 hours after LTx (9.0% vs. 41.6% p = 0.001). This group also spent a mean of 5 days less in the ICU (p = 0.004) and 5 days less in hospital (p = 0.046). In conclusion, PRP PRP completion halved the risk of cumulative mortality in patients with IPF undergoing unilateral LTx.

High-resolution computed tomography findings of pulmonary tuberculosis in lung transplant recipients / Achados de tuberculose pulmonar na tomografia computadorizada de alta resolução em transplantados de pulmão

ABSTRACT Objective: Respiratory infections constitute a major cause of morbidity and mortality in solid organ transplant recipients. The incidence of pulmonary tuberculosis is high among such patients. On imaging, tuberculosis has various presentations. Greater understanding of those presentations could reduce the impact of the disease by facilitating early diagnosis. Therefore, we attempted to describe the HRCT patterns of pulmonary tuberculosis in lung transplant recipients. Methods: From two hospitals in southern Brazil, we collected the following data on lung transplant recipients who developed pulmonary tuberculosis: gender; age; symptoms; the lung disease that led to transplantation; HRCT pattern; distribution of findings; time from transplantation to pulmonary tuberculosis; and mortality rate. The HRCT findings were classified as miliary nodules; cavitation and centrilobular nodules with a tree-in-bud pattern; ground-glass attenuation with consolidation; mediastinal lymph node enlargement; or pleural effusion. Results: We evaluated 402 lung transplant recipients, 19 of whom developed pulmonary tuberculosis after transplantation. Among those 19 patients, the most common HRCT patterns were ground-glass attenuation with consolidation (in 42%); cavitation and centrilobular nodules with a tree-in-bud pattern (in 31.5%); and mediastinal lymph node enlargement (in 15.7%). Among the patients with cavitation and centrilobular nodules with a tree-in-bud pattern, the distribution was within the upper lobes in 66.6%. No pleural effusion was observed. Despite treatment, one-year mortality was 47.3%. Conclusions: The predominant HRCT pattern was ground-glass attenuation with consolidation, followed by cavitation and centrilobular nodules with a tree-in-bud pattern. These findings are similar to those reported for immunocompetent patients with pulmonary tuberculosis and considerably different from those reported for AIDS patients with the same disease.

RESUMO Objetivo: As infecções respiratórias constituem a principal causa de morbidade e mortalidade em transplantados de órgãos sólidos. A incidência de tuberculose pulmonar é alta entre esses pacientes. Em exames de imagem, a tuberculose tem diferentes apresentações. Uma maior compreensão dessas apresentações poderia reduzir o impacto da doença ao facilitar o diagnóstico precoce. Portanto, buscamos descrever os padrões de tuberculose pulmonar na TCAR em transplantados de pulmão. Métodos: De dois hospitais no sul do Brasil, foram coletados os seguintes dados sobre transplantados de pulmão que desenvolveram tuberculose pulmonar: sexo; idade; sintomas; doença pulmonar que levou ao transplante; padrão na TCAR; distribuição dos achados; tempo entre transplante e tuberculose pulmonar; e taxa de mortalidade. Os achados na TCAR foram classificados como nódulos miliares; cavitação e nódulos centrolobulares com padrão de árvore em brotamento; atenuação em vidro fosco com consolidação; linfonodomegalia mediastinal; ou derrame pleural. Resultados: Foram avaliados 402 transplantados de pulmão, dos quais 19 desenvolveram tuberculose pulmonar após o transplante. Entre esses 19 pacientes, os padrões mais comuns na TCAR foram atenuação em vidro fosco com consolidação (em 42%); cavitação e nódulos centrolobulares com padrão de árvore em brotamento (em 31,5%); e linfonodomegalia mediastinal (em 15,7%). Entre os pacientes com cavitação e nódulos centrolobulares com padrão de árvore em brotamento, esses achados se distribuíam nos lobos superiores em 66,6%. Não se observou derrame pleural. Apesar do tratamento, a mortalidade em um ano foi de 47,3%. Conclusões: O padrão predominante na TCAR foi atenuação em vidro fosco com consolidação, seguido por cavitação e nódulos centrolobulares com padrão de árvore em brotamento. Esses achados são semelhantes aos relatados para pacientes imunocompetentes com tuberculose pulmonar e consideravelmente diferentes dos relatados para portadores de AIDS com a mesma doença.

Advances in Imaging and Automated Quantification of Pulmonary Diseases in Non-neoplastic Diseases.

Histological examination has always been the gold standard for the detection and quantification of lung remodeling. However, this method has some limitations regarding the invasiveness of tissue acquisition. Quantitative imaging methods enable the acquisition of valuable information on lung structure and function without the removal of tissue from the body; thus, they are useful for disease identification and follow-up. This article reviews the various quantitative imaging modalities used currently for the non-invasive study of chronic obstructive pulmonary disease, asthma, and interstitial lung diseases. Some promising computer-aided diagnosis methods are also described.

Functional improvement in patients with idiopathic pulmonary fibrosis undergoing single lung transplantation.

OBJECTIVE: To evaluate the changes in lung function in the first year after single lung transplantation in patients with idiopathic pulmonary fibrosis (IPF). METHODS: We retrospectively evaluated patients with IPF who underwent single lung transplantation between January of 2006 and December of 2012, reviewing the changes in the lung function occurring during the first year after the procedure. RESULTS: Of the 218 patients undergoing lung transplantation during the study period, 79 (36.2%) had IPF. Of those 79 patients, 24 (30%) died, and 11 (14%) did not undergo spirometry at the end of the first year. Of the 44 patients included in the study, 29 (66%) were men. The mean age of the patients was 57 years. Before transplantation, mean FVC, FEV1, and FEV1/FVC ratio were 1.78 L (50% of predicted), 1.48 L (52% of predicted), and 83%, respectively. In the first month after transplantation, there was a mean increase of 12% in FVC (400 mL) and FEV1 (350 mL). In the third month after transplantation, there were additional increases, of 5% (170 mL) in FVC and 1% (50 mL) in FEV1. At the end of the first year, the functional improvement persisted, with a mean gain of 19% (620 mL) in FVC and 16% (430 mL) in FEV1. CONCLUSIONS: Single lung transplantation in IPF patients who survive for at least one year provides significant and progressive benefits in lung function during the first year. This procedure is an important therapeutic alternative in the management of IPF.
