Bronchoscopic lung volume reduction (BLVR) is a novel emphysema therapy. We evaluated long-term outcome in patients with heterogeneous emphysema undergoing BLVR with one-way valves.40 patients undergoing unilateral BLVR entered our study. Pre-operative mean forced expiratory volume in 1 s (FEV1) was 0.88 L?s -1 (23%), total lung capacity was 7.45 L (121%),intrathoracic gas volume was 6 L (174%), residual volume (RV) was 5.2 L (232%), and the 6-min walk test (6MWT) was 286 m. All patients required supplemental oxygen; the Medical Research Council (MRC) dyspnoea score was 3.9. High-resolution computed tomography (HRCT) results were reviewed to assess the presence of interlobar fissures. 33 patients had a follow-up of .12 months (median 32 months). 37.5% of the patients had visible interlobar fissures. 40% of the patients died during follow-up. Three patients were transplanted and one underwent lung volume reduction surgery. Supplemental oxygen, FEV1, RV, 6MWT and MRC score showed a statistically significant improvement (pf0.0001, p50.004, p50.03, p50.003 and p,0.0001, respectively). Patients with visible fissures had a functional advantage.BLVR is feasible and safe. Long-term sustained improvements can be achieved. HRCT-visible interlobar fissures are a favourable prognostic factor.
Inflammatory myofibroblastic tumors (IMT) of the lung are considered rare and benign; however, involvement of adjacent thoracic organs, local recurrence and distant metastases have been described. The potential presence of distant metastases supports the hypothesis that those tumors should not be considered 'clinically' benign, although histological features suggest this attitude; thus, complete resection and careful follow-up are mandatory. We present a case of a bilateral pulmonary IMT with left adrenal gland metastasis in a patient with dyspnea and cough.
To date, no comprehensive marker to monitor the immune status of patients is available. Given that Torque teno virus (TTV), a known human virome component, has previously been identified as a marker of immunocompetence, it was retrospectively investigated whether TTV viral load may also represent a marker of ability to develop antibody in response to COVID-19-BNT162B2 vaccine in solid organ transplant recipients (SOT). Specifically, 273 samples from 146 kidney and 26 lung transplant recipients after successive doses of vaccine were analyzed.
An inverse correlation was observed within the TTV copy number and anti-SpikeIgG antibody titer with a progressive decrease in viremia the further away from the transplant date. Analyzing the data obtained after the second dose, a significant difference in TTV copy number between responsive and nonresponsive patients was observed, considering a 5 log 10 TTV copies/mL threshold to discriminate between the two groups. Moreover, for 86 patients followed in their response to the second and third vaccination doses a 6 log 10 TTV copies/mL threshold was used to predict responsivity to the booster dose. Although further investigation is necessary, possibly extending the analysis to other patient categories, this study
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
