Recurrence of lymphangioleiomyomatosis: Nine years after a bilateral lung transplantation

引用

World Journal of Transplantation 2016年第1期6卷 249-254页

作者： Khawaja S Zaki Zahra Aryan atul c mehta Olufemi Akindipe Marie Budev Respiratory Institute Cleveland Clinic Lerner college of Medicine Bouncore Family Endowed Chair in Lung Transplantation Cleveland Clinic

Lymphangioleiomyomatosis(LAM) is a rare, slowly progressive lethal lung disease primary afflicting young women. LAM is characterized by proliferation of abnormal smooth muscle cells that target the lungs, causing cystic destruction and eventual respiratory failure leading to death. Recent ten year mortality due to end stage LAM has been reported to be approximately 10%-20%, but may vary. The decline in lung function in LAM is gradual, occurring at a rate of about 3% to 15% per year but can vary from patient to patient. But recently therapy with mammalian target of rapamycin(m TOR) inhibitors such as sirolimus has shown promising results in the stabilization of lung function and reduction of chylous effusions in LAM. Lung transplantation is a viable option for patients who continue to have decline in lung function despite m TOR therapy. Unique issues that may occur post-transplant in a recipient with LAM include development of chylous effusion and a risk of recurrence. We describe a case of LAM recurrence in a bilateral lung transplant recipient who developed histological findings of LAM nine years after transplantation.

AIM: To evaluate frequency and temporal relationship between pulmonary nodules(PNs) and transbronchial biopsy(TBBx) among lung transplant recipients(LTR). METHODS: We retrospectively reviewed 100 records of LTR who underwent flexible bronchoscopy(FB) with TBBx, looking for the appearance of peripheral pulmonary nodule(PPN). If these patients had chest radiographs within 50 d of FB, they were included in the study. Data was compared with 30 procedures performed among non-transplant patients. Information on patient's demographics, antirejection medications, anticoagulation, indication and type of lung transplantation, timing of the FB and the appearance and disappearance of the nodules and its characteristics were ***: Nineteen new PN were found in 13 procedures performed on LTR and none among nontransplant patients. Nodules were detected between 4-47 d from the procedure and disappeared within 84 d after appearance without ***: FB in LTR is associated with development of new, transient PPN at the site of TBBxin 13% of procedures. We hypothesize that these nodules are related to local hematoma and impaired lymphatic drainage. close observation is a reasonable management approach.

Organic solar cells(OScs) hold great potential as a photovoltaic technology for practical ***, the traditional experimental trial-and-error method for designing and engineering OScs can be complex, expensive, and time-consuming. Machine learning(ML) techniques enable the proficient extraction of information from datasets, allowing the development of realistic models that are capable of predicting the efficacy of materials with commendable accuracy. The PM6 donor has great potential for high-performance OScs. However, it is crucial for the rational design of a ternary blend to accurately forecast the power conversion efficiency(PcE) of ternary OScs(TOScs) based on a PM6 ***, we collected the device parameters of PM6-based TOScs and evaluated the feature importance of their molecule descriptors to develop predictive models. In this study, we used five different ML algorithms for analysis and prediction. For the analysis, the classification and regression tree provided different rules, heuristics, and patterns from the heterogeneous dataset. The random forest algorithm outperforms other prediction ML algorithms in predicting the output performance of PM6-based TOScs. Finally, we validated the ML outcomes by fabricating PM6-based TOScs. Our study presents a rapid strategy for assessing a high PcE while elucidating the substantial influence of diverse descriptors.
