Objectives: We reviewed the utility of rigid bronchoscopy in the management of complications resulting from placement of metallic endobronchial stents after lung transplantation.
Methods: A retrospective review was performed of all lung transplant patients who required metallic endobronchial stenting between 2005 and 2009. The patients' medical records were reviewed, and details regarding stent placement, complications, and removal were recorded.
Results: A total of 43 metallic stents were placed in 22 patients who had unilateral or bilateral lung transplantation. Stent complications occurred in 18 cases (42%) at a mean of 285 days after placement and included stent collapse, stent breakdown, stent migration, ingrowth of granulation tissue, and coughing up of fractured pieces of stent. Of the 43 stents placed, only 4 (9%) had to be removed. Removal was readily accomplished by rigid bronchoscopic techniques, even when some endothelial ingrowth had occurred.
Conclusions: Lung transplantation presents unique challenges in airway management. Endobronchial stenting plays an important role in the management of anastomotic stenosis and bronchomalacia in these patients. Although metallic stents have significant advantages, complications often arise that occasionally necessitate their removal. Rigid bronchoscopy is a valuable tool in the management of endobronchial stent complications after lung transplantation.

Impact of pulmonary rehabilitation on survival in people with Interstitial lung disease.
Chest

Background: Pulmonary rehabilitation (PR) is a beneficial intervention for people with interstitial lung disease (ILD), however the effect of PR on survival is unclear. This study compared the survival outcomes in people with ILD who were allocated to PR versus those who were allocated to control in two published randomised controlled trials (RCTs).
Research Question: Does participation in PR impact survival among people with ILD?
Study Design And Methods: The combined data from the two previous RCTs of PR in ILD were included.

Background: Bronchiectasis is a disease with a global impact, but most published data come from high-income countries. We aimed to describe the clinical characteristics of patients with bronchiectasis in China.
Methods: The Chinese Bronchiectasis Registry (BE-China) is a prospective, observational cohort enrolling patients from 111 hospitals in China.

Impact of sex hormones on pheochromocytomas, paragangliomas, and gastroenteropancreatic neuroendocrine tumors.

Objective: The effects of sex hormones remain largely unexplored in pheochromocytomas and paragangliomas (PPGLs) and gastroenteropancreatic neuroendocrine tumors (GEP-NETs).
Methods: We evaluated the effects of estradiol, progesterone, Dehydroepiandrosterone sulfate (DHEAS), and testosterone on human patient-derived PPGL/GEP-NET primary culture cell viability (n = 38/n = 12), performed next-generation sequencing and immunohistochemical hormone receptor analysis in patient-derived PPGL tumor tissues (n = 36).
Results: In PPGLs, estradiol and progesterone (1 µm) demonstrated overall significant antitumor effects with the strongest efficacy in PPGLs with NF1 (cluster 2) pathogenic variants.
Association of Grit and Resilience With Short-Term Post-Transplant Outcomes in Lung Allograft Recipients.

The importance of mental toughness on lung transplant outcomes is unknown. We performed a pilot study to assess whether pretransplant grit and resilience are associated with short-term posttransplant outcomes. We enrolled 31 lung transplant candidates, of whom 7 (26%) had greater mental toughness, defined as the upper tertile for both grit and resilience within our cohort.
